Simple Definition Of Kinetic Energy In Physics

Kinetic energy kinetic energy is the energy of motion.

Simple definition of kinetic energy in physics. Si unit of kinetic energy is joules and there are five types of kinetic energy. It may be considered as energy relating to temperature. Kinetic energy is defined as the energy of an object when it is moving from the state of rest to motion. Any object in motion is using kinetic energy.

It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity having gained this energy during its acceleration the body maintains this kinetic energy unless its speed changes the same amount of work is done by the body when decelerating from its current. Other units for energy include the newton meter nm and the kilogram meter squared over seconds squared kg m 2 s 2. Potential energy this is energy due to an object s position. It is a scalar quantity.

In physics the kinetic energy ke of an object is the energy that it possesses due to its motion. A person walking a thrown baseball a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work. In relativistic physics kinetic energy is equal to the product of the increase of mass caused by motion times the. A swinging pendulum has kinetic energy.

Naturally the kinetic energy of an object at rest should be zero. The joule is the standard unit for energy in general. Kinetic energy is a scalar quantity which means it only has a magnitude and not a direction. Kinetic energy a bowling ball has kinetic energy when it is moving.

Heat heat or thermal energy is energy from the movement of atoms or molecules. For example a ball sitting on a table has potential energy with respect to the floor because. Thomas young 1773 1829 derived a similar formula in 1807 although he neglected to add the to the front and he didn t use the words mass and weight with the same precision we do nowadays. Thus an object s kinetic energy is defined mathematically by the following equation.
