What do all moving objects have?
Kinetic energy.
1 of 9
When does the amount of kinetic energy increase?
The greater the mass and the faster the speed of the object.
2 of 9
What is the kinetic enrgy equation?
Ek = 1/2 x m x v squared.
3 of 9
What does 'Ek' stamd for? Units?
Kinetic energy in Joules, J
4 of 9
What does 'm' stamd for? Units?
Mass in kilograms, Kg
5 of 9
What does 'v' stamd for? Units?
Speed in metres per second, m/s
6 of 9
What is a elastic object?
One that regains it shape after being stretched or squashed.
7 of 9
What is elastic potential energy?
Energy stored in an elastic object when work is done to change its shape.
8 of 9
Why does a spring warm up if it is stretched/squashed?
Some elastic potential energy is transferred by heating.
