Question

write three equations of motion and three laws of motion. class 9​

Answer 1

Answer:

The three equations are, v = u + at. v² = u² + 2as. s = ut + ½at²

Answer 2

Answer:

EQUATIONS:

v = u + at

v² = u² + 2as

s = ut + ½at²

LAWS:

Newton’s first law - if a body is in the state of rest or is moving with a constant speed in a straight line, then the body will remain in the state of rest or keep moving in the straight line, unless and until it is acted upon by an external force.  

Newton’s second law - the rate of change of momentum of a body is directly proportional to the force applied on it, and the momentum occurs in the direction of the net applied force.

Newton’s third law - to every action, there is always an equal and opposite reaction.
