definition for first law of motion, second law, third law of motion
Answers
Explanation:
First rule : Each body remains in a state of uniform motion in its resting state or in a straight line until an external force forces it to behave otherwise. It is also called the law of inertia . [2] [3] [4]
Second law : The rate of change of momentum of any body is proportional to the force exerted and its direction of (momentum change) is the same.
f = mv-mu / t = m (vu) / t = ma
=f = mv-mu / t
f = m (vu) / t
f = ma (vu) / t = a
Third Rule : Every action always reacts in equal and opposite direction.
Answer:
Explanation: first law of motion- Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Newton's third law is: For every action, there is an equal and opposite reaction.
