WebAug 18, 2024 · 1st Law – This law states that until external pressure is added, a body stays in its rest state or continuous motion in a straight line. 2nd Law – According to the second law, a body accelerates due to unbalanced forces around it. This acceleration depends on the mass of the object and the net force applied. WebApr 3, 2024 · Rolling friction. Each object receives a contact force; whenever the surface of one object slides over the surface of another. This contact force, which always opposes relative motion between the two surfaces, is called frictional force. The frictional force is applied tangentially to the two-body interface.
