what is force and laws of motion explain briefly ?
Answers
Answer:
Force: It is a push or pull on an object that produces acceleration in the body on which it acts. ... (b) It can change the direction of motion of a body. (c) It can change the shape of a body.
The first law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force. Mathematically, this is equivalent to saying that if the net force on an object is zero, then the velocity of the object is constant.
Newton's second law
The second law states that the rate of change of momentum of a body over time is directly proportional to the force applied, and occurs in the same direction as the applied force.
Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. ... If a body has a net force acting on it, it undergoes accelerated motion in accordance with the second law.
