explain motion with all points
Answers
Answer:
In physics, motion is the change in position of an object with respect to its surroundings in a given interval of time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, and speed. Motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.
If the position of an object is not changing with respect to a given frame of reference (reference point), the object is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position with reference to its surroundings. Momentum is a quantity which is used for measuring the motion of an object. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in an isolated system (one not affected by external forces) does not change with time, as described by the law of conservation of momentum. An object's motion cannot change unless it is acted upon by a force.
