1
Q
constant speed on a distance time graph
A
A straight line represents constant speed
2
Q
changing speed on a distance time graph
A
.If the slope is increasing, the speed is increasing (accelerating)
.If the slope is decreasing, the speed is decreasing (decelerating)
3
Q
decreasing slope
A
means decreasing speed
4
Q
increasing slope
A
means increasing speed
5
Q
what’s the relationship between average speed, distance moved and time taken
A
average speed=distance moved/timetaken
6
Q
what’s the relationship between acceleration, change in velocity and time taken
A
acceleration= change in velocity/time taken
7
Q
gradient on a velocity time graph
A
means acceleration
8
Q
flat line on a velocity time graph
A
means constant speed
9
Q
negative gradient in a time velocity graph
A
means deceleration
