Question

Rate of change of momentum is proportional to the exerted force and takes place in the direct in which the force acts.’ is a statement of Newton’s

1 point

(a) first law of motion

(b) second law of motion

(c) third law of motion

(d) all the three laws of motion

​

Answer 1

Answer:

Newton's Second Law –

The rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force. The resultant force is equal to the rate of change of momentum.

Explanation:

Answer 2

Answer:

b) second law of motion

Explanation:

The object is either at rest and the velocity is zero, or it moves in a straight line with a constant speed. The acceleration of an object is parallel and directly proportional to the net force acting on the object, is in the direction of the net force and is inversely proportional to the mass of the object.
