### Slide 2

change in potential energy = mass × gravitational field strength × change in height

PE = m × g × h

The towers are 30m tall and the cars will be

1000Kg in mass. What will the Potential

energy be at the top of the tower?

A ski jumper waits

144m above

stadium. What

mass is she if her

potential energy is

72000J?

An 80Kg man clears a 5m pole just.

What is his PE as he clears the pole

and when he lands on the mat

### Slide 3

kinetic energy = ½ × mass × (velocity) 2

Kinetic Energy KE = ½ mv 2

This is movement energy. The more kinetic energy an object has the faster it will

move.

A Person(50Kg) ran the first part of a race

at a speed of 5m/s. They then walked the

last part at a speed of 2m/s. What is their

kinetic energy for both parts?

Both the truck and the bike were travelling at

the same speed. Which had the most kinetic

energy?

Problems of kinetic & potential

### Slide 4

Conservation of Energy

Roller Coaster starts at top of hill stationary. It has

lots of stored potential Energy. As it starts to roll

the PE goes down and the KE goes up. At the

bottom of the hill the car has Max KE but no PE

Spot the mistake!

Why does the PE not go to zero?
