Question

What is a motion?? And three laws of motion.

Happy Janmashtami friends.
Good morning​

Answer 1

Answer:

motion definition:-Motion, in physics, change with time of the position or orientation of a body. ... In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

Laws:- (1) Every object moves in a straight line unless acted upon by a force.

(2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass.

(3) For every action, there is an equal and opposite reaction.

Answer 2

Answer:

Motion :- An object is said to be in motion if it changes it's position with respect to surroundings and with time.

Ex:- All the planets revolving around the sun.

Molecules of a gas in motion above 0k.

Three Newton's laws of motion :-

Newton's first low of motion states that :- ‘An object remains in a state of rest or in uniform motion in a straight line unless compelled to change that state by an applied force.’

Newton's second law of motion states that :- ‘The rate of change of momentum of an object is proportional to the applied force in the direction of force.’

Newton's third low of motion states that :- ‘To every action there is an equal and opposite reaction and the act on two different bodies.’
