- Work Done
The work-energy principle states that the net work done on an object changes its kinetic energy. While work done by propulsive forces, such as driving force of an engine, increases kinetic energy, work done against resistive forces, such as forces from the brakes, will cause kinetic energy to be lost. Considering the work-
24 sty 2024 · The object loses energy due to the work done against resistive forces. The line of action of a force refers to the point of application of the force and the direction the force was applied in. Work is a scalar quantity, it has size without direction.
work-energy principle is very useful: The change in the total energy of the particle is equal to the work done on the particle. When approaching questions where an external force acts on a particle, the general procedure is to:
Learn that the work-energy principle states that the work done on an object is equal to the change in its kinetic energy. Remember that work done is calculated as the force applied on the object multiplied by the distance over which the force is applied (in the direction of the force).

7 lip 2023 · Use the Work-Energy Principle to find the speed with which it impacts the wall. You can find the speed by making the kinetic energy the subject. This gives the speed of impact. To find the speed of rebound, calculate "e" × the speed of impact.
