Joules
5
Q
How many newton-metres in 1 Joule
A
1 newton-meter = 1 Joule
6
Q
Describe the energy transfer when work is done
A
Work is done on an object when a force of one Newton causes the object to be displaced by one metre
7
Q
Is work done if the force acting on an object is moving in the same direction as the object?
A
Yes
8
Q
Is work done if the force acting on an object is moving in a diffrent direction to the object?
A
No, they must be moving in the same direction
