(8 cards)
1
Q
distance
A
refers to how far you have travelled from your start to finish point, regardless of direction
- measured in terms of ‘total distance covered’
2
Q
displacement
A
measures the overall change in position of a person and is measured in magnitude and direction
3
Q
speed
A
measure of the distance an object travels per unit of time, representative of how quickly you cover a certain distance
4
Q
velocity
A
speed in a given direction, a change in velocity could be representative of a change in speed, direction or both
5
Q
acceleration
A
rate at which the velocity of a body changes in respect to time
6
Q
positive acceleration
A
velocity is increasing
7
Q
negitive acceleration
A
- retardation
velocity is decreasing
8
Q
zero acceleration
A
no change in velocity
