WebSep 12, 2024 · The net work done on a particle equals the change in the particle’s kinetic energy: Wnet = KB − KA. Figure 7.4.1: Horse pulls are common events at state fairs. The work done by the horses pulling on the load results in a change in kinetic energy of the load, ultimately going faster. (credit: “Jassen”/ Flickr) Web4 years ago. Actually both the formula's still produce the same answer, since the initial velocity is 0. When the initial velocity is 0 then the displacement=final velocity. Initial velocity = 0. Final velocity = 2 km/h. Total time = 2 h. Avg velocity = Iv + Fv/2. Avg velocity = 0+2/2. Avg velocity = 1 km/h.

WebThe change in velocity is v – u, which is 30 – 10 = 20 m/s. The acceleration is the change in velocity ÷ time, which is 20 m/s ÷ 4 s = 5 m/s 2.. Question WebVelocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance. It is the rate of change of displacement. Speed of an object moving can never be negative.
