In a distance-time graph, what is represented on the horizontal axis?
Time
Distance
Speed
In a distance-time graph, what is represented on the vertical axis?
In a distance-time graph, what is represented by the gradient of the graph?
True or false? The formula for calculating speed is time/distance.
True or false? Vehicles that have to drive for long distances are fitted with devices called tachographs to ensure they do not drive for too long.
What type of quantity is velocity?
Vector (magnitude and direction)
Scalar (magnitude)
True or false? A body which changes direction is accelerating.
Which of these is the correct formula for working out acceleration?
a = t/(v-u)
a = (v-u)/t
a = t/(u-v)
a = (u-v)/t
True or false? The unit of acceleration is metres per second.
True or false? Deceleration is simply negative acceleration.
