Review Q #2

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What happens to gravitational potential energy (GPE) when an object is raised to a higher position?

Back

The gravitational potential energy increases.

Front

What is kinetic energy?

Back

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

Front

How does energy transfer occur in a roller coaster?

Back

Energy transfers between gravitational potential energy and kinetic energy as the coaster moves.

Front

What is the relationship between potential energy and kinetic energy on a slope?

Back

As potential energy decreases, kinetic energy increases.

Front

What is an example of an action-reaction pair in swimming?

Back

When a swimmer pushes against the wall, the wall pushes back with equal force.

Front

What is gravitational potential energy (GPE)?

Back

Gravitational potential energy is the energy stored in an object due to its height above the ground.

Front

What happens to the total mechanical energy in a closed system?

Back

The total mechanical energy remains constant.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the effect of friction on energy transfer?

Back

Friction converts kinetic energy into thermal energy, reducing the total mechanical energy.
