What is MotionWhen a body does not change its position with time, we can say that the body is at rest, while if a body changes its position with time, it is said to be in motion.Analysing Linear Motion Linear motion is motion in a straight line.Non-line…

Difference Between Speed And VelocityThe ‘distance’ travelled by a body in unit time interval is called its speed. When the position of a body changes in particular direction, then speed is denoted by ‘velocity’. i.e. the rate of change of displacement …

What is SpeedWhen we say a body moves fast (or slow) we refer to its speed.The speed of an object is defined as the distance travelled by it in unit time. .The SI unit of speed is metre per second (m/s).Therefore, an object that moves faster covers more…
