Explanation:
When the body is in non-uniform motion When a body moves with non-uniform speed it covers unequal distance in equal intervals of time. The distance-time graph for a body which is moving with non-uniform speed is not a straight line. It is a curve. The speed of the object will change with respect to time.Explanation:
Velocity depends on magnitude and direction since it is vector quantity, as the direction changes velocity changes while the speed remains the same velocity can be equal to speed if the body is in linear motion[motion in straight line] but it cannot exceed speed.Explanation:
Actually acceleration is rate of change of velocity. A body, when at rest, has zero velocity and since it is not moving or about to move so it's acceleration is also zero. When average velocity is zero then the average acceleration and instantaneous acceleration both are zero.Explanation:
In a straight line path displacement is equal to distance.Explanation:
Displacement is always less than or equal to the distance traveled, so it cannot be greater than the distance. if they are the same direction, then their magnitude will be equal, however, if they have different directions then displacement will be less than the distance.
