what is Kinetic energy class 9 science , work and energy #shorts

Work || Kinetic energy

Assertion :- According work energy theorem net work done on a body is equal to change in its kinetic energy. Reason :- The work energy theorem is independent of Newton's second law.

What is the kinetic energy of an object ?

What is meant by kinetic energy?

Develop the notions of work and kinetic energy and show that it leads to work-energy theorem.

Kinetic Energy OF Rigid Body and Work-Energy Theorem-1

what are the units of work and energy ?

When a body is projected vertically up. At some point P at height h its kinetic energy is twice of potential energy at that point. At what height its potential energy is twice that of kinetic energy?

A : The potential energy of a system increases when work is done by conservative force. R : Kinetic energy can change into potential energy and vice-versa.

In the Bohr's orbit, what is the ratio of total kinetic energy and total energy of the electron
