(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.
WebChapter 5 – Force and Motion I I. Newton’s first law: If no net force acts on a body, then the body’s velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially.
WebAug 8, 2024 · When an object is moving with constant velocity, it means that there is 0 acceleration and hence no force and no work done. But, this is only partly true. Generally an object, when it moves with constant velocity, is overcoming some friction and some force is being applied to balance it. chinese rockaway njWebNear the surface of Earth, the gravitational force on an object of mass m has a constant magnitude, mg, and constant direction, vertically down.
