There is Work done = 10 × 2 = 20 J. The triangle above may help you to rearrange the equation. Work done has the same units as energy - joules. This is because energy is the ability to do work. So you. Find the power delivered to the truck. [Given: 1000 kg as the mass of the truck] First we need to calculate the work done, which requires the force necessary to lift the truck against gravity: F = mg = 1000 x 9.81 = 9810 N. W = Fd = 9810N x 2m = 19620 Nm = 19620 J

Friction would do negative work and thus remove mechanical energy from the falling ball. Use the following diagram to answer questions #3 - #5. Neglect the effect of resistance forces. 3. As the object moves from point A to point D across the surface, the sum of its gravitational potential and kinetic energies ____ Since work is the change in kinetic energy, calculate the work done by each force.The work can be positive, nega-tive, or zero, depending on the relative angles of the force and displacement of the object.The sum of the three works is the change in energy of the system.
