Force, Motion, and Energy Review 6.8A & 6.8BC

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its velocity.

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, an object at a height has gravitational potential energy.

How does energy transform when a roller coaster cart goes up a hill?

Back

As the cart goes up, kinetic energy is converted into potential energy, causing the cart to slow down.

Front

What happens to the kinetic energy of an object as it slows down?

Back

The kinetic energy decreases as the object slows down.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

If a bus travels 20 km in 30 minutes, what is its average speed?

Back

The average speed is 40 km/h.

Front

What is the relationship between height and gravitational potential energy?

Back

Gravitational potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

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.

Front

How can you classify energy in a moving car?

Back

A moving car has kinetic energy due to its motion.
