Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

Balanced forces always cause no motion. True or False?

Back

False. Balanced forces do not cause a change in motion, but they can still be in motion.

Front

What are the two types of forces?

Back

Contact Forces and Non-contact Forces.

Front

What is an example of a contact force?

Back

A bowling ball knocking over pins is an example of a contact force.

Front

What is an example of a non-contact force?

Back

Gravity is an example of a non-contact force.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What happens when forces are unbalanced?

Back

Unbalanced forces cause a change in motion, such as starting, stopping, or changing direction.

Front

If a couch is pushed with 45 N to the right, what is the net force?

Back

The net force is 45 N to the right.

Front

What is potential energy?

Back

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

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.
