What is Sir Isaac Newton's second law of motion?

Answer 1

Sir Isaac newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, this is represented by the equation F = ma, where F is the net force applied to the object, m is the mass of the object, and a is the acceleration produced. This law helps us understand how the motion of an object changes when a force is applied to it.

Answer 2

1. First law: Every body remains in a state of constant velocity unless acted upon by an external unbalanced force.This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant velocity.
2. Second law: A body of mass m subject to a net force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.
3. Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This law is sometimes referred to as the action-reaction law, with F called the "action" and −F the "reaction". The action and the reaction are simultaneous.

Answer 3

the rate of change of momentum of a body is proportional to the impressed force and takes place in the direction in which the force acts.

Answer 4

for every action there is an equal and opposite re action
