Question Answer
Acceleration The rate of change in speed (or velocity), measured in metres per second squared. Acceleration = change of velocity ÷ time taken.
Deceleration Slowing down or negative acceleration, eg the car slowed down with a deceleration of 2ms^-2.
Displacement Quantity describing the distance from the start of the journey to the end in a straight line with a described direction, eg the hiker ended up at the hostel 50km due north of his original position
Force A push or a pull. The unit of force is the newton (N).
Magnitude The magnitude tells us the size of the vector.
Momentum A quantity relating to a moving object that is calculated by multiplying its mass by its velocity.
