Displacement

Distance. Time graph
If an object moves along a straight line, the distance travelled can be represented by a distance-time graph.
Acceleration
The change in velocity per second is known as the acceleration of a body
Force
A force causes a stationary object to move
Contact forces
Two objects have to be in contact for these forces to occur
Non-contact force
Two object do not have to be in contact for these forces to occur
Interaction pair
This is when one thing applies pressure to a surface
Newton meter
Forces can be measured by it
Force meter
A digital way to measure force
