1

What is the equation for gravitational potential energy?

gravitational potential energy = Mass(kg)*g*height(m)
g = gravitational field strength (10 N/kg for earth)

2

What is gravitational potential energy?

The energy that an object has by virtue of its vertical position in a gravitational field

3

When an object is raised vertically, [ ] against the [ ] and the object gains gravitational potential energy.

work is done
force of gravity

4

What is force of gravity measured in?

Joules (J)

5

What is the formula for kinetic energy?

kinetic energy (J) = 1/2 * mass (kg) * speed² (m/s)

6

What does kinetic energy depend on?

Mass and speed
