GPE mass x gravity x height.

Physics energy equations. Therefore in a simple way temperature is how hot or cold an object is. Position of any object. Other questions will ask you to use the Physics Equation Sheet.

The expression for the energy of a photon is thus. This is a set. Work done force x distance.

Society Fall 2007 Physics of Energy I - 2 One thing we already know is that energy comes in many different forms. It is the sum total of potential energy and kinetic energy which is the energy associated with the motion. Some questions in the exam will require you to recall and apply equations you have learned in class.

Thermal energy - heat. Energy voltage x current x time. Click on the equation for more information.

13122020 German physicist Max Planck determined that the energy of a photon is proportional the frequency f with which it vibrates and he calculated the constant of proportionality h which is called Plancks constant in his honor. WFs W F s. G PE m gh.

Total energy in x 100. Objects have mechanical energy if they are in motion andor if they are at some position relative to the surface. Energy voltage x charge.

E V x I x t. Links Electricity Revision Questions. On the other hand when it is at rest then its kinetic energy will be zero.

PEmgh m is the mass g is the gravitational acceleration and h is the distance Potential Energy of the Spring. Gravitational Potential Energy mass x gravity x height. W V x Q work voltage x charge.

Kinetic energy - the energy of motion. The equations work whether the electricity is direct current or alternating current. Also kinetic energy is possessed by an object due to work done by it for its movement.

Download What You See Below. Mechanical Energy Kinetic Energy Potential Energy. K E.

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. 2speed2 E K 1 2 mv GPE mass. Also the temperature is the average kinetic energy per molecule of that substance.

We can make a list. Energy Equations to Learn kinetic energy 1 2. K is the spring constant and x is the amount of compression or streching.

Total energy in x 100. Kinetic Energy 0. Kinetic Energy 05 x mass x velocity 2.

Heat is a form of energy which produces a change in the temperature of any substance. When an object is moving then its potential energy considered zero. E V x I x t energy voltage x current x time.

13052021 Physics energy equations questions Bf text textbf Powerfrac text textbf energy transferred text textbf time Power timeenergy transferred. That means that for a twofold increase in speed the kinetic energy will increase by a factor of four. Energy Efficiency useful energy out.

E p for an object with a mass m a height h from the ground and gravitational field strength g98Nkg. WFs W F s. Height 𝑃 ℎ power work done time taken energy transferred time taken efficiency useful energy output total energy input efficiency useful power output total power input Equations given in the exam.

The law of conservation of energy is one of the basic laws of Physics. Total cost number of units x cost per unit. Energy equations Need to know.

Chemical energy - stored in eg. Therefore the formula of mechanical energy will be. See the sections below including equations from motion forces energy momentum electricity and waves.

Efficiency useful energy out. Gravitational field strength. KE mv 2.

For a threefold increase in speed the kinetic energy will increase by a factor of nine. W F x d. Our equation sheet from various sections of physics.
