Centripetal Acceleration

Centripetal Acceleration

The Acceleration associated with uniform circular motion is called a centripetal acceleration. Let a particle of mass (m), moving with a constant speed (v), angular velocity (ω), on a circular path of radius r with centre O. Let at any time t, the particle be at P, and at time t+∆t the particle be at […]

Uniform Circular Motion

Uniform Circular Motion

When an object follows a circular path at a constant speed, the motion of the object is called uniform circular motion. Although the speed does not very, the particle is accelerating because the velocity changes its direction at every point on the circular track. Example:- Motion of the tip of the second hand of the

Projectile motion

Projectile Motion

Projectile motion is a form of motion in which an object or particle is thrown with some initial velocity near the earth’s surface and it moves along a curved path under the action of gravity alone. The path followed by projectile is called its trajectory. An object that is in flight after being thrown is

Acceleration is defined as the ratio of change in velocity and the corresponding time interval. Average Acceleration It is defined as the change in velocity (∆v) divided by the corresponding time interval (∆t). Instantaneous Acceleration It is defined as the limiting value of the average acceleration as the time interval approaches to zero. Motion In
