Front

What are forces that change the motion of an object?

Back

Unbalanced forces are forces that cause an object to change its motion.

Front

What is the time interval when a wind-up toy stopped during a 10-second travel test?

Back

The toy stopped between 5-7 seconds.

Front

What is the definition of force?

Back

A force is a push or pull that can change the motion of an object.

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is motion?

Back

Motion is the change in position of an object over time.
