Give any two differences between speed and velocity? What is retardation? Why is is dangerous to get down from moving bus? What is momentum? Give its unit also.If Someone answer correct I will mark you as brainlisted promise​

Answer 1

Answer:

Explanation:

2  The inertia of motion causes the passenger of a bus to fall down or temporarily lose his balance as he tries to jump out of the moving bus.

It is because the inertia of motion of the body appears to resist the change in the state of the body when the passenger jumps, because it prefers to remain in the state of motion of the bus instead of coming to a resting state.

 3  Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motionThe units for momentum would be mass units times velocity units. The standard metric unit of momentum is the kg•m/s.

Answer 2

Explanation:

For more than a week of rainy weather, Crusoe is seriously ill with a fever and severe headache. He is almost too weak to get up for water, though he is dying of thirst. He prays to God for mercy. In one of his feverish fits, he hallucinates a vision of a man descending from a black cloud on a great flame.
