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
What is Speed and How to Calculate Speed
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 distance in a second (unit time) as compared to an object that moves slower.Different Units of … [Read more...] about What is Speed and How to Calculate Speed
