Web30 sep. 2015 · Force is a push or a pull, and the displacement of an object due to the application of a force on it is work. The ability to do work is called energy. Explanation: … WebPotential Energy Graphs and Motion - Key takeaways. When we visualize the potential energy as a function of the object's position in a graph, we find that the force is the …

WebWe know that by F=−dU/dx formula that when force is attractive in nature potential energy increases and when force is repulsive, potential energy decreases. How increasing or … Web29 apr. 2014 · Energy is the ability to do work and work changes the energy of objects. Work requires the application of force over a distance to achieve that change in energy. A book on the floor has zero potential energy. When I pick it up and put it on the table, I do work on the book because I gave it more potential energy. Work = change in energy. tsotsi novel questions and answers

Web10 apr. 2024 · Energy must be transferred to an object to help it move, and the energy can be transferred in the form of force. The energy transferred by force to move any object is known as work or work done. Therefore, work and energy have a direct relationship. The difference in the kinetic energy of an object is called work done by the object. WebPotential Energy and Conservative Forces. Work is done by a force, and some forces, such as weight, have special characteristics. A conservative force is one, like the gravitational force, for which work done by or against it depends only on the starting and ending points of a motion and not on the path taken. We can define a potential energy … tsotsi short questions and answers
