What is Motion When 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 MotionLinear motion is motion in a straight line. Non-linear motion is motion that is not in a straight line. When analysing linear and non-linear motion, … [Read more...] about What is Motion and Types of Motion

What Is The Difference Between Speed And Velocity
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 of a body is called its Velocity. Speed is a scalar quantity while velocity is a vector quantity. Unit: In … [Read more...] about What Is The Difference Between Speed And Velocity
