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