When a ball is thrown inside a moving bus, does its kinetic energy depend on the speed of the bus ? Explain.

When speed of the ball is doubled its kinetic energy is

When a charged particle moves in a magnetic field, does its kinetic energy always remain constant? Explain.

What kind of energy does a speeding bus have?

An object thrown from a moving bus is on example of

An object thrown from a moving bus is an example of:

How does the kinetic energy of a moving body depend on its (i) speed, and (ii) mass ?

When you lift a box from the floor and put it on an almirah the potential energy of the box increases bu there is no change in its kinetic energy. Is it violation of conservation of energy ? Explain. (AS_(7))
