MOTION IN GRAPHS

Point A – B = Time is increasing to the right, and distance is
increasing constantly with time. The object moves at a constant speed.

Point B – C = Time is increasing to the right, but its distance does not
change. It is not moving. We say it is At Rest.

Point C – D = Time is increasing to the right, and distance is
increasing constantly with time. The object moves at a constant speed and
returning to the initial position.

Point D – E = The line on this graph is curving upwards. This shows an increase
in speed, since the line is getting steeper:
In other words, in a given time, the distance the object moves is
change (getting larger). It is accelerating.

A CAR IS INCREASING ITS SPEED
