## Kinetic Energy

In physics, the ** kinetic energy (KE)** of an object is the

*that it has due to its motion. It is*

**energy***defined*as the work needed for an object of a known

**mass**to

**accelerate**to a given velocity.

In physics, the ** kinetic energy (KE)** of an object is the

**Specific heat capacity** is how much heat **energy** is required to raise 1 **kg** of a substance by 1 **°C**.

The quantity **power** is the rate at which work is done. The quicker work is done the greater the **power**.

Stretching or squashing an object can transfer energy into its **elastic potential energy store**.

The size of the **current** is the rate of flow of **charge**. Electrons are negatively charged particles which transfer **energy** through wires as electricity.

**Resistance** is an electrical quantity that measures how a device or material reduces the electrical **current** flow through it.

Resistors in series and in parallel can change the total **resistance** in a circuit.

The **power **of an appliance is the **energy** that is transferred per **second**. Electric **power** is the rate, per unit time at which electrical **energy** is transferred by an electric circuit.

**Density** is a measure of how compact the particles are in a substance. **Density** is defined as the mass per unit volume.

**Specific latent heat** is the **energy **needed to change the state of a substance.
