PRACTICE: KE & PE 2024

Front

What two factors affect KINETIC energy?

Back

Mass and velocity.

Front

What is ELASTIC POTENTIAL ENERGY?

Back

The energy stored in elastic materials as the result of their stretching or compressing.

Front

How do you calculate gravitational potential energy (GPE)?

Back

GPE = mass × gravity × height.

Front

What is the formula for KINETIC energy?

Back

KE = 1/2 × mass × velocity².

Front

Which has more KINETIC energy: a fast-moving car or a slow-moving car of the same mass?

Back

The fast-moving car has more KINETIC energy.

Front

What happens to KINETIC energy as an object speeds up?

Back

The KINETIC energy increases.

Front

What is the relationship between height and gravitational potential energy?

Back

Higher objects have more gravitational potential energy.

Front

What is an example of a situation with high ELASTIC POTENTIAL ENERGY?

Back

A stretched rubber band.

Front

At which point is KINETIC energy greatest in a roller coaster ride?

Back

At the lowest point of the track.

Front

What is the difference between KINETIC energy and POTENTIAL energy?

Back

KINETIC energy is the energy of motion, while POTENTIAL energy is stored energy based on position.
