Question

what is kinetic energy derive an equation for kinetic energy of a body of mass M and moving at a speed v

Answer 1

The formula for Kinetic Energy is as follows:

KE= ½⋅m⋅v²

where:

KE is the kinetic energy

m is the mass of the object

v is the velocity

Kinetic Energy is the energy that exists in a moving body at a specified velocity or the energy required to accelerate a body to a specified velocity.

The above links are to a kinetic energy calculator that lets you enter the mass and velocity in various different units. The calculator does automatic unit conversions.

kinetic energy=(1/2)m(v^2)

m=mass

v=velocity

this is for linear motions .If we consider about angular motions, it becomes

kinetic energy=(1/2)*moment of inertia*(angular velocity^2)

angular velocity=linear velocity/radius of the motion
