- 1P3a - Speedaverage speed = distance/time
We write 'average speed' because the speed of the car changes during a journey. - 2The speed of a car at a certain point in time is called instantaneous speed.distance travelled = average speed x time
d = (u + v) ÷ 2 × t
d is the distance
u is the starting speed
v is the finishing speed
t is the time taken - 3—You should be able to rearrange the equation.
- 4Distance Time GraphsDistance time graphs allow a collection of data to be shown.
The gradient of a distance-time graph tells you about the speed of the object. A higher speed = steeper gradient.
A straight line indicates that the speed is constant. - 5—For the blue line the speed is...
Distance/time=speed
Distance = 10
Time = 2s
10/2=5m/s
