WebWhen your car is moving at constant velocity down the street, the net force must also be zero according to Newton’s first law. The car’s engine produces a forward force; friction, a force between the road and the tires of the car that opposes forward motion, has exactly the same magnitude as the engine force, producing the net force of zero. WebOne situation where friction plays an obvious role is that of an object on a slope. ... An object slides down an inclined plane at a constant velocity if the net force on the object is zero. ... When two rough surfaces are in contact, the actual contact area is a tiny fraction of the total area because only high spots touch. When a greater ...

WebFigure 7.3 Work done by a constant force. (a) A person pushes a lawn mower with a constant force. The component of the force parallel to the displacement is the work done, as shown in the equation in the figure. (b) A person holds a briefcase. No work is done because the displacement is zero. WebSince Newton's first law states that when the net force is zero, the object maintains a constant velocity. And for the net force to be zero, these forces have to cancel. So, even though it's non-intuitive, this cable force has to equal the force of gravity, so that the elevator can move with constant velocity.
