Can a force set a motionless object in motion

WebNov 5, 2024 · A motionless object still has constant (zero) velocity, so motionless objects also have zero acceleration. Newton’s second law states that: \[\mathrm{∑F=ma}\] so objects with constant velocity also have zero net external force. This means that all the forces acting on the object are balanced — that is to say, they are in equilibrium. WebMay 26, 2024 · Work is positive if the direction fo the force is the same as the direction of the displacement of the object. Positive work transfers energy to the object. In your first example you did positive work of 50 Joules on the block. Negative work occurs if the direction of the force is opposite to the displacement of the object.

Friction arises in part because of the roughness of the surfaces in contact, as seen in the expanded view. For the object to move, it must rise to where the peaks of the top surface can skip along the bottom surface.

WebJun 27, 2024 · Inertia is the tendency of an object to resist changes in its state of motion. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity – and (in the absence of an unbalanced force) will remain with a zero velocity.
