Unit 3 Checkpoint 1 Review

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate or change its motion. It occurs when the net force acting on an object is not zero.

Front

What type of energy do people sitting on a bench mostly have?

Back

People sitting on a bench mostly have kinetic energy, as they are not moving significantly. However, they also have potential energy due to their position.

Front

What happens when two teams pull with the same amount of force?

Back

If two teams pull with the same amount of force, they will not move at all because the forces are balanced.

Front

Does an arrow drawn back in a bow have potential energy?

Back

Yes, an arrow drawn back in a bow has mostly potential energy because it is stored energy due to its position.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects with less effort.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or condition, such as height above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is the net force?

Back

The net force is the total force acting on an object when all the individual forces are combined.

Front

What does it mean for forces to be balanced?

Back

Forces are balanced when they are equal in size and opposite in direction, resulting in no change in motion.
