For a toy train travels at a steady speed of 0.2 ms-1 around a circular track, the change in speed from a to b will be constant.
A circular motion is a movement of an object along the circumference of a circle or rotation along a circular path.
In a uniform circular motion the speed is constant. However, since it is moving in a circle, the direction of motion continuously changes.
This will result to a change in the velocity of the object.
Thus, for a toy train travels at a steady speed of 0.2 ms-1 around a circular track, the change in speed from a to b will be constant.
