what is motion and work
Answers
motion is a change in position of an object over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, time, and speed.
work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force.
Q1. What is Motion?
Ans. The general study of the relationships between motion, forces, and energy is called mechanics. ... Motion is the action of changing location or position. The study of motion without regard to the forces or energies that may be involved is called kinematics. It is the simplest branch of mechanics.
Q2. What is work?
Ans. Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. ... No work is done in either case.
