Which of the following is equal to the gradient of a distance-time graph at a given point in time?Total distance travelledSpeedAccelerationDisplacement2An object is at rest.  What will its distance-time graph look like?It will be a curveIt will be a horizontal lineIt will be a straight line of positive gradient (it will slope upwards to the right)It will be a straight line of negative gradient (it will slope downwards to the right)3An object accelerates uniformly from rest.  What will its distance-time graph look like?It will be a curve of increasing positive gradient (one which gets steeper as time increases)It will be a curve of decreasing positive gradient (one which gets less steep as time increases)It will be a straight line of negative gradient (it will slope downwards to the right)It will be a straight line of positive gradient (it will slope upwards to the right)4Car A is travelling at a steady speed of 10 m/s, and car B is travelling at a steady speed of 20 m/s.  How will the distance-time graphs for the motion of both cars compare with one another?The graph for car A will be twice as steep as the graph for car BThe graph for car B will be twice as steep as the graph for car AThe distance travelled by car A at a given point in time will be twice that travelled by car B at the same point in timeBoth graphs will have the same gradient5(HT) An object is accelerating.  How can its speed at a given point in time be measured using a distance-time graph of its motion?Divide the total distance travelled at that point by the time takenCalculate the total area under the graph up to that point and divide this value by the timeDraw a tangent to the line at that point and then calculate the gradient of the tangentMultiply the total distance travelled at that point by the time taken

Identify what the slope of a distance-time graph indicates.Distance travelledHeightAccelerationSpeed

The gradient of a distance / time graph tells us:

What does the slope of the distance-time graph give?a. speedb. velocityc. accelerationd. displacement

An object's acceleration describes its change in speed. If the speed of an object increases with time, its graph will have a gradient. If an object slows down, its graph will have a gradient.
