…The size of the turning effect is called a **turning** **moment**. As Newton's first law of motion states, an object will remain at rest if the forces are balanced. When the sum of the forces add to zero, a body will remain at rest or move at a constant **velocity**.

Forces can cause an object to rotate and the **turning effect of the force is called a moment**. If a **resultant force **acts on an object about a fixed turning point called the **pivot** or **fulcrum** it will cause the object to rotate e.g. using a spanner, a screwdriver, opening a door hanging on hinges.

When a force acts on a spring it is stretched or compressed, its length will changes by an amount e from its original length.

…**Pressure** can be calculated if you know the **force** applied to or by an object and the contact **area**. The units are **newtons** per square meter, or **N/m ^{2}**.

An object of constant **mass** accelerates in proportion to the **force** applied.

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**.
