Define work in physics for kids
WebThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy.

WebJun 13, 2024 · Physicists, the scientists who study quantum physics, discovered that everything in the universe behaves like both a particle and a wave. This concept revealed one of the most powerful ideas in ... WebThe spring force is a contact force and a restoring force that is also conservative. There is an interaction between the spring and the object attached to it. The spring forces restores the object to equilibrium when it is displaced. The work done by the spring only depends on the object's initial and final position.
WebApplying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed. The energy transferred is known as kinetic energy , and … WebKids learn about glossary and terms in the science of physics and motion. Definitions for words such as momentum, force, work, energy, gravity, scalar, vector, power, and more. ... Work - Work occurs in physics when a force acts on an object to move it some distance. Work is equal to the force times the distance and is measured in joules.
WebEnergy is another word for power. Energy makes things move. It makes machines work. Energy also makes living things grow. WebPhysics is about more than just objects and forces.
