David was sitting in his hotel room reading a book, when he heard a knock at the door, and the sound of someone trying the door handle. He opened the door, where he saw a man whom he had never seen before. The man said, "I'm terribly sorry... I thought this was my room. Wrong floor, I guess. He then walked
off down the hall toward the elevator. David went back into his room, thought about what had just happened, and then phoned the front desk, suggesting they
call the police, since the man at the door had obviously been a thief.
Why was David so sure the man had been a thief?

it is called kinetic energy

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
