What happens when a force moves an object?
Energy is transferred and work is done.
1 of 13
How do you calculate work done?
Work Done=Force applied (N) * Distance moved in the direction of the force (m)
2 of 13
What happens when an object is lifted up?
Work is done against the force of gravity; its weight.
3 of 13
How do you calculate the change in gravitational potential energy?
Change (J)=Weight (N) * Change in vertical height (m)
4 of 13
What is gravitational potential energy?
The energy stored in an object because of the height it has been lifted to, against the force of gravity.
5 of 13
What is elastic potential energy?
The energy stored in an elastic object when work has been done on the object to change its shape (e.g. catapult)

When a car brakes; what is kinetic energy transformed into?
Heat in brakes and tyres

In a wind turbine; what is kinetic energy transformed into?
Electricity; heat and sound

When a space shuttle re-enters the atmosphere; what is kinetic energy transformed into?
Heat
11 of 13
When does an object have more kinetic energy?
If it has a bigger mass or if it travels at a higher speed
