Non Uniform Circular Motion If the speed of the particle in a horizontal circular motion changes with respect to time, then its motion is said to be non-uniform circular motion. Consider a particle describing a circular path of radius r with center at O. let at an instant the particle be at P and be Read more about Non Uniform Circular Motion[…]

Energy of Projectile A body which is in flight through the atmosphere under the effect of gravity alone and is not being propelled by any fuel is called projectile. If the force acting on a particle is oblique with initial velocity then the motion of particle is called projectile motion. When a projectile moves upwards Read more about Energy of Projectile[…]

Stopping Distance When an object is moving with a certain velocity then suddenly brakes are applied, and then object stops completely after covering a certain distance. This is called as stopping distance. It is the distance travelled between the time when an object deiced to stop a moving vehicle and the time when the vehicle Read more about Stopping Distance[…]
