Explanation:
Detailed explanation-1: -mechanics, science concerned with the motion of bodies under the action of forces, including the special case in which a body remains at rest.
Detailed explanation-2: -DESCRIBING MOTION Motion is defined as the change in position over an interval of time. Students will therefore describe motion in terms of the positions of the moving object at different points in time, or its distance travelled over a period, or its speed of travel.
Detailed explanation-3: -The object is considered to be in uniform motion since its velocity (Y-axis value) does not change at any point in time (X-axis value). If an object’s speed-time graph is a straight line parallel to the time axis, it is said to be moving.
