Kinetic Energy and Potential Energy

Front

What is the energy of stretched or compressed objects called?

Back

Elastic Potential Energy

Front

How do you calculate Gravitational Potential Energy (GPE)?

Back

GPE = weight (N) × height (m)

Front

What is the formula for Kinetic Energy (KE)?

Back

KE = 0.5 × mass (kg) × (velocity (m/s))^2

Front

What is the GPE of an object at the top of an 8-m slide with a weight of 50 N?

Back

400J

Front

What is the GPE of an object at 4-m on an 8-m slide with a weight of 50 N?

Back

200J

Front

What is the GPE of an object at 2-m on an 8-m slide with a weight of 50 N?

Back

100J

Front

If a runner weighing 60 kg runs at a speed of 5 m/s, what is their Kinetic Energy?

Back

750J

Front

What type of energy does an object have when it is at rest at a height?

Back

Potential Energy

Front

What happens to the GPE of an object as it descends?

Back

The GPE decreases as the height decreases.

Front

What is the relationship between Kinetic Energy and speed?

Back

Kinetic Energy increases with the square of the speed.
