Work and energy quiz 1

Name :

If a body does work to left a wight to height of 10 meter then at maximum height the work would equal numerically to

From the previous example at the height of 5 meter mechanical energy =

What will happen to the kinetic energy if the velocity is doupled

If a body falls from the top of the building and ( d ) is the distance from the top of the mountain then as ( d ) increases what happen to the potential energy

If two boxes A and B mass of box A is double the mass of box B and height of box A is double the height of box B then the ratio between potential energy of A to that of B
