To stop a moving object, a force must act in the opposite direction to the direction of motion. For instance, if you push your book across your desk, the book… Read More »FRICTIONAL FORCES

Newton’s first law (law of inertia) This law states that “A body continues in its state of rest or uniform motion unless an unbalanced force acts on it”. The mass… Read More »NEWTON LAWS OF MOTION
