Question

what is motion? plss tell​

Answer 1

Answer:

• Motion, in physics, change with time of the position or orientation of a body.
• Motion along a line or a curve is called translation.
• In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

Answer 2

Answer:

n physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The 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 with change in time. The branch of physics describing the motion of objects without reference to its cause is kinematics; the branch studying forces and their effect on motion is dynamics.

If an object is not changing relatively to a given frame of reference, the object is said to be at rest, motionless, immobile, stationary, or to have a constant or time-invariant position with reference to its surroundings. As there is no absolute frame of reference, absolute motion cannot be determined
