Energy stored by an object because it is moving.
Revise: Changes in energyA moving object has a kinetic energy store: a rolling ball, for example, has kinetic energy because it is moving.
Energy associated with the motion of a particle; particles moving or vibrating more rapidly have more kinetic energy.
Define internal energy using both parts: the total kinetic energy and potential energy of all the particles in the system.
Keep particle energy and temperature distinct: temperature is related to the average kinetic energy of the particles, whereas internal energy is the total kinetic and potential energy of all the particles.
When explaining a change of state, state where the transferred energy goes: it changes the particles’ potential energy rather than raising their average kinetic energy.

The energy an object has because it is moving, calculated using .
Revise: Factors Affecting Stopping DistanceA faster vehicle has more kinetic energy.
The energy stored by a moving object; it depends on the object's mass and the square of its speed.
The amount of energy in the kinetic store of a moving object, measured in joules (J).
The energy associated with an object because it is moving.
The energy associated with the movement of an object or particle.

Revise: Particle motion and pressureThe temperature of a gas is linked to the average kinetic energy of its molecules. Molecules in any sample have a range of speeds, so heating does not make every molecule move at exactly the same speed. Instead, their average kinetic energy increases and they move faster on average.
The energy stored by a moving object because of its motion.
Energy associated with an object's movement, measured in joules (J).

The energy associated with a moving object; it depends on the object's mass and the square of its speed.
Revise: Kinetic and Gravitational Potential EnergyA moving object has energy in its kinetic energy store. An object raised above ground level has energy in its gravitational potential energy store. Both quantities are measured in joules (J).
The energy stored by a moving object.
Energy associated with motion; rapidly moving fission products and neutrons carry kinetic energy.
Energy associated with the movement of an object or particle.
The energy an object or particle has because it is moving.
Energy possessed by a particle because it is moving or vibrating.
The energy an object or particle has because it is moving.
