State mewton s three low of motion with proof,examples and it's application
Answers
Answer:
First law of motion: An object tends to stay in its state of rest or uniform motion unless an external force is applied on it
Second law of motion: The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction o the force
third law: Every action has an equal n opposite reaction
Answer:
The first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... And if an additional external force is applied, the velocity will change because of the force. Example: The motion of a kite when the wind changes can also be described by the first law.
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass. Example: Riding your bicycle is a good example of this law of motion at work.
The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Example: As a professor paces in front of a whiteboard, he exerts a force backward on the floor. The floor exerts a reaction force forward on the professor that causes him to accelerate forward.
