Question

what is motion?when a body is said to be in motion.​

Answer 1

Explanation:

motion means when a body changes its position from one point to other

body is said to be in a state of motion when it is moving or equivalently its position continuously changes with respect to time.

Answer 2

• A body is only deemed to be in motion when its location changes in relation to an observer.
• When two bodies move together, their positions change, even if one is at rest with relation to the other.
• Motion is defined as a change in the position of an item over time.
• Motion may be quantified using terms such as displacement, distance, velocity, acceleration, speed, and time.
• An observer is given a frame of reference, and the shift in the body's position in relation to that frame is tracked over time.
• Kinematics is the discipline of physics that investigates objects' motion independent of their source, whereas dynamics is the branch that analyses forces and their consequences on motion.
