1)when its distance from another object is changing
2)This means that the object does not cover equal distances in equal time intervals. If the motion is not consistent in the case of rectilinear motion, the acceleration of the body will be non-zero. For example, the motion of a vehicle is an oscillation of a pendulum. Non-uniform motion is also called accelerated motion.
3)Speed is defined as the rate of change of distance with time. It has the dimension of distance by time. ... Thus, the SI unit of Speed is meter per second. In everyday life, kilometer per hour or in countries like US and UK miles per hour are used as the unit of speed.
4)The most major drawback of sundial is that it cannot be used in the night.
5)Average speed is calculated by the formula S = d/t,
The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.
