At rest and in motion are relative terms. When we say 'in motion' or 'at rest' we mean relative to something else. If you were travelling in a car for instance, you would be at rest relative to the car but in motion relative to the outside world.
When an object changes its position with respect to time, then the body is said ti be in 'motion'. When the body is at rest, it is state of 'no motion'.
newton's first law of motion is also known as LAW OF INERTIA. inertia is the property of a body by which every body if is in rest it tends to remain in rest and if in motion it tends to remain in motion.
Newton's First Law - A body at rest will remain rest, and a body in motion will maintain its motion at constant velocity unless acted on by an unbalanced force. (often called the law of inertia). Newton's Second Law - The acceleration of a body is directly proportional to the net force acting on it and inversely proportional to its mass. Newton's Third Law - If a body A exerts a force on body B, at the same time body B exerts an equal and opposite force on body A. This means all forces exist in pairs.
Mechanics, which has two parts. Statics - Science of bodies at rest. Dynamics - Science of body/ies in motion.
With respect to a state of rest or apparent rest.
the tendency of a body at rest to remain at rest and of a body in motion to remain in motion
no when the body the body is in motion only
MOTION: A body is said to be in motion if it changes it's position with respect to it's surrounding. REST: A body is said to be in rest if it does not changes it's position with respect to it's surrounding.
motion : when a body is moving or changing its position with respect to its surroundings is called motion. rest: when a body is not moving or fixed at a place with respect to its surroundings is called rest.
A body is said to be in motion or at rest w.r.t. its surroundings. A person in bus is at rest wrt another person in same bus. He is in motion wrt bus stop.
When an object changes its position with respect to time, then the body is said ti be in 'motion'. When the body is at rest, it is state of 'no motion'.
Inertia. Newton's First Law of Motion: "A body at rest tends to stay at rest, while a body in motion tends to stay in motion."
An unbalanced force.
'An object said to be at rest when it is not in motion'.The above statement has been proved by Newton's First Law of Motion (Law Of Inertia) , it says When a body is at rest it tends to be at rest and when a body is inmotion it tends to be in motion until an external force is applied on it.
Newton's first law states that a body at rest will remain at rest and a body in motion will remain in motion in a straight line at constant velocity unless acted upon by an unbalanced force. So the two parts involve a body at rest and a body in motion.
A body at rest and a body in motion have completely different velocities.Magnitude of velocity:At rest . . . zeroMoving . . . not zeroDirection of velocity:At rest . . . no directionMoving . . . some direction
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion in a straight line at constant velocity unless acted upon by an unbalanced force.
