Answer:

motion is a change in position of an object over time. Motion is described in terms of displacement , distance, velocity, acceleration, timeand 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.

Answer:

1-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.

2-Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.

3-An object is said to be at rest if it does not change its position with respect to its surroundings with time.

4-Distance is a numerical measurement of how far apart objects or points are.

5-Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude.

6-Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path.

Hope it helps
