What is the unit of measurement for energy?

Back

Joules (J)

Front

What is the formula for calculating kinetic energy (KE)?

Back

KE = 0.5 * mass * velocity^2

If a car has a mass of 1120 kg and is traveling at 40 m/s, what is its kinetic energy?

Back

896,000 J

Front

How much kinetic energy does a 0.3 kg marble moving at 6 m/s have?

Back

5.4 J

What is the kinetic energy of a 1 kg pie being thrown at 4 m/s?

Back

8 J

Front

Define gravitational potential energy (GPE).

Back

The energy an object possesses due to its height above the ground, calculated as GPE = mass * gravity * height.

Front

What is the formula for total mechanical energy (TME)?

Back

TME = Kinetic Energy (KE) + Gravitational Potential Energy (GPE)

Front

What happens to kinetic energy if the velocity of an object doubles?

Back

The kinetic energy increases by a factor of four, since KE is proportional to the square of the velocity.

Front

What is the gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².
