What is the equation involving force, distance and work done?

• Work = Force x distance

• Force = Work x Distance

• Distance = Work x Force

W= 125 J

d= 10 m

Force=???

• 0.125N

• 12.5N

• 1250N

• 135N

When a pendulum swings, at which point is potential energy at its greatest

• 1

• 2

• 3

• 4

What is the equation involving:

Gravitational potential energy, gravitational field strength, mass and height

• Gravitational field strength = mass x gravitational potential energy x height

• Mass = Gravitational potential energy x gravitational field strength x height

• Gravitational Potential Energy = mass x gravitational field strength x height

Roger Federer’s tennis ball has a weight of 0.4kg. Gravitational field strength on Earth is 10N/kg. If he holds the ball above the ground at a height of 2.0 m to serve, what is its gravitational potential energy (GPE)?

• 0.5J

• 2J

• 8J

• 4J
