2) Write down Newton's law of motion and examples each.
Answers
Answer:
Law 1. A body continues in its state of rest, or in uniform motion in a straight line, unless acted upon by a force.
Law 2. A body acted upon by a force moves in such a manner that the time rate of change of momentum equals the force.
Law 3. If two bodies exert forces on each other, these forces are equal in magnitude and opposite in direction.
Explanation:
Answer:
Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force. eg:- action occurs in friction newton's 2nd law:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely
proportional to the mass of the object. eg:-If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.
newton's 3rd law : For every action, there is an equal and opposite reaction.
eg:- action of inertia
