Newton's first and second law with explination​

Answer 1

Answer:

Newton's first and second law of motion an object on which no net force is acting is not necessarily at rest, the object could be moving with a constant velocity.......

it states that the acceleration of the object is directly proportional to the net force acting on the object and inversely proportional to the objects of mass.

Answer 2

Answer:

Newton first law states that “A body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it”. Suppose a block is kept on the floor, it will remain at rest until we apply some external force to it. Also, we know that it takes us more effort or force to move a heavy mass. This is directly related to a property known as Inertia. This law is also known as the law of inertia.

According to Newton’s second law of motion, the net force experienced by a body is directly proportional to the rate of change of momentum of the body.
