Answer:
1. In 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
Explanation:
2. An object's position is its location relative to a reference point (or origin of a coordinate system). Position is a vector quantity because it does have a direction.
3. The only difference between velocity and speed is that velocity has a direction. Displacement is the distance moved in a straight line, or a given direction from the starting point. If a car travels 24 m east in 3 seconds, what is its velocity
4. acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing.
