Acceleration increase in the velocity of an object
Average speed the total distance travelled divided by the time taken (t)
Average velocity the total displacement divided by the time taken (t)
Balanced when two forces combine to cancel each other out
Contact force the object generating the force must be touching the object being acted upon
Deceleration decrease in the velocity of an object
Displacement the shortest distance between the starting point and the finishing point
Distance how far an object has travelled
Force push or pull
Friction force that opposes motion
Gravity attraction between two masses
Mass the amount of matter in an object
Newton a unit of force (N)
Non-contact force the object generating the force does not need to be touching the object being acted upon
Speed how fast an object is travelling
Stationary an object that is not moving
Unbalanced when two forces do not cancel each other out
Velocity the displacement divided by the time taken
Weight force caused by gravity on an object
