1
Q

What is meant by “work done”?

A

When a force moves an object through a distance, energy is transferred and work is done.

2
Q

How do you calculate the work done?

A

Work done = Force x Distance

3
Q

How do you calculate gravitational potential energy?

A

Gravitational Potential Energy = mass x gravity x height

4
Q

What is the formula for kinetic energy?

A

kinetic energy = 1/2 x mass x speed squared.

5
Q

How do you slow down the kinetic energy of a car?

A

The kinetic energy has to be converted to heat energy as friction causing the temperature to increase.
