- I can show an understanding of forces by calculating the net force acting on an object and describe the motion of the object due to the forces acting on it.
- balaced forces
- unbalanced force
- net force
Any push or pull is a force. To describe a force, you must know two things. You must know the size of the force and the direction of the force. Suppose two teams are playing tug of war. Each team is pulling with equal force, but in opposite directions. Neither team can make the other team move. Forces that are equal in size but opposite in direction are called balanced forces.
Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.
Unbalanced forces are not equal and opposite. Suppose that one of the teams in tug of war pulls harder than the other team. The forces would no longer be equal. One team would be able to pull the other team in the direction of the larger force.
More than one force can act on an object at the same time. If you hold a paper clip near a magnet, you, the magnet and gravity all exert forces on the paper clip. The combination of all the forces acting on an object is the net force. When more than one force is acting on an object, the net force determines the motion of the object. In this example, the paper clip is not moving, so the net force is zero.
How do forces combine to form the net force? If the forces are in the same direction, they add together to form the net force. Suppose you and a friend are asked to move a piano for the music teacher. To do this, you pull on one end of the piano, and your friend pushes on the other end. Together, your forces add up to enough force to move the piano. This is because your forces are in the same direction. Because the forces are in the same direction, they can be added together to determine the net force. When forces act against each other, or in opposite directions, the forces are subtracted.
Calculating Net ForceNet Force is the total amount of force acting on an object. When one or more forces act together, the applied force are added. When forces act against each other, or in opposite directions, the forces are subtracted.

In this image there is 100 Net Force pushing to the right + 100 Net Force pushing to the right which = 200 Net Force. The force is unbalanced so the box will move to the right.

In this image there is 200 Net Force pushing toward the right and 400 Net Force pushing toward the left. The difference is 200 Net Force pushing toward the left. The forces are unbalanaced and the box will move toward the left.

In this image, the forces are all 100. The forces are balanced and so the box will not move.

In this unit there is a net force of 200 pushing to the right and a net force of 200 pushing to the left. The two forces are balanced and so, the box will not move.

Forces are needed to lift, turn, move, open, close, push, pull, and so on. When you throw a ball, you are using force to make the ball move through the air.
More than one force can act on an object at the same time. Think about all the different forces you need to ride your bike. Your feet push on the pedals, your hands push and pull the handlebars, and the muscles in your body help you stay balanced. The tires are pushing against the pavement, while the pavement is pushing back on them. Wow, that’s a lot of forces!
why is it important that the different systems works together properly?

Does this photo show unbalanced or balanced forces? Explain why.
Possible Answers:
The photo represents unbalanced forces because there are more players on one side of the rope than the other.
This photo represents balanced forces because both teams have an equal number of players, and they are of similar size.
The photo represents balanced forces because both sides are balancing carefully while holding the ropes.
This photo represents unbalanced forces because the forces are not even on both sides, so there is an unbalance.
Correct answer:
This photo represents balanced forces because both teams have an equal number of players, and they are of similar size.
Explanation:
This photo represents a balanced force because each side has an equal number of participants, and they are of similar size. It appears that they are both pulling equally, and they have the same strength. If both sides pull with an equal amount of force, then neither team will move, and it will be a tie.
What does the term balanced forces mean? Example: James and Noora were both pulling on a tug toy with their dog, and because of balanced forces, neither side was able to move the other!
Possible Answers:
Two forces are acting in the same direction on an object, and equal in size.
Two forces are acting the same direction on an object, and unequal in size.
Two forces acting in opposite directions on an object, and equal in size.
Two forces are acting in opposite directions on an object, and unequal in size.
Correct answer:
Two forces acting in opposite directions on an object, and equal in size.
Explanation:
Balanced forces are two forces acting in opposite directions on an object, and equal in size. In the example, James and Noora have the same force or strength as their dog, so neither side can pull the toy away from the other. If one party were stronger than the other, there would be an unbalanced force, and the stronger team would be able to take the toy away from the weaker side.
Which direction would this object move with balanced forces working on it?
Possible Answers:
Correct answer:
It would not move.
Explanation:
This object would not move because it has balanced forces working in it. When balanced forces are applied to opposite sides of an object, the object remains motionless. A stronger force needs to be applied to one side for the object to move. Balanced forces mean the power or strength applies to each side is equal.
This graphic represents a balanced force.
Possible Answers:
Explanation:
The graphic provided does not represent a balanced force. A balanced force means equal forces are being applied to each side of an object. The arrows would need to be equivalent to represent a balanced force. There is more force being applied in one direction than the other, so the object will move in with force.
What is the effect of a balanced force on a stationary object's motion?
Possible Answers:
There is no effect on the motion.
The object will move upwards away from the forces.
The object will move in the direction of the weakest force.
The object will move in the direction of the strongest force.
Correct answer:
There is no effect on the motion.
Explanation:
A balanced force means that equal force is being applied to an object on opposite sides. If equal force is being applied, there will be no change in the motion of the object; it will remain stationary. A greater force needs to be applied to one side for movement to take place.
The groups of people in this photo are both pulling on a rope. Which group will win the tug-of-war game?
Possible Answers:
The group on the left side will win.
The group on the right side will win.
Correct answer:
Neither group will win.
Explanation:
This photo represents a balanced force because each side has an equal number of participants, and they are of similar size. It appears that they are both pulling equally, and they have the same strength. If both sides pull with an equal amount of force, then neither team will move, and it will be a tie. In this graphic, neither team will win.
What does this photo represent in terms of forces?
Possible Answers:
Correct answer:
Balanced forces
Explanation:
This photo represents balanced forces. When balanced forces are applied to opposite sides of an object, the object remains motionless. A stronger force needs to be applied to one side for the object to move. Balanced forces mean the power or strength applies to each side is equal.
How do equal forces on an object affect an object's motion?
Possible Answers:
Equal forces will cause an object to move upwards.
Equal forces will cause an object to remain in place.
Equal forces will cause an object to move quickly to the left.
Equal forces will cause an object to move quickly to the right.
Correct answer:
Equal forces will cause an object to remain in place.
Explanation:
Equal forces are two forces acting in opposite directions on an object, same in strength, and equal in size. If one party is stronger than the other, there would be an unbalanced force. An object will not move if balanced forces are applied to it.
Which scenario represents an example of balanced forces affecting an object's motion?
Possible Answers:
Bill needed to move his dresser across the room, so he pushed it across the wood floor.
My two Boston Terrier puppies tug on either side of a stuffed toy all day long!
Neil pushed off with his left foot and skated across the ice gracefully.
Jessica and Fiona each tug a rope on either side. Jessica is eight years old, and Fiona is fifteen.
Correct answer:
My two Boston Terrier puppies tug on either side of a stuffed toy all day long!
Explanation:
When balanced forces are applied to opposite sides of an object, the object remains motionless. The example "My two Boston Terrier puppies tug on either side of a stuffed toy all day long!" demonstrates two dogs that are of similar strength and size pulling on opposite sides of the toy. These dogs are applying the same power and force on both sides of the toy, and neither can pull the toy away from the other.
This graphic represents an unbalanced force.
Possible Answers:
Explanation:
This image represents balanced forces. Each person is pushing in opposite directions with equal strength and power. The box will not move because there are balanced, equal forces on both sides.
