Velocity-Time graph gives two most important parameter. 1) Its slope gives the acceleration. 2. The area under the curve gives the distance traveled by an object.Here we will derive velocity(v = u + at) equation as shown the figure. And we will also derive graphically distance (s = ut + 1/2 a t2) equation. Analytically…

Displacement-Time graph is important to interpret mathematical expression into picture as a graph. Graph gives a short cut idea about the concept of the mathematical statement. In Displacement time graph the slope of the curve is the velocity. If the curve is straight line then it means that the velocity is constant. In a graph…

Speed: Speed is the rate at which an object covers a distance. Speed is a scalar quantity. It has no direction . Velocity: Velocity may be defined as the rate of change of displacement. Or It can be also defined as : “ rate of change of position of an object.” Velocity is a vector…

Rest: A body is said to be at rest when it does not change its position with respect to their environment and time. For example house, tower, tree etc. MOTION: A body is said to be in motion when it changes its position with respect to environment and time. For example moving car, walking man…

Types of Motion: Rest: A body is said to be at rest when it does not change its position with respect to their environment and time. For example house, tower, tree etc. Motion:A body is said to be in motion when it changes its position with respect to environment and time. For example moving car,…

To specify the position of an object, we need a point with respect to which we identify the position of that object. This point is known as the origin or reference point. Consider a man starts walking from point O. First he goes to point P and then to point Q. as we can see…
