The **SPEED** of an object is explained using an *equation*, yes maths, we have to do maths in science! :(

The **SPEED** equation is... **SPEED = DISTANCE ÷ TIME... REMEMBER THIS!**

**---------------------------------------------------------------------------------------------------**

The **unit** we use for **SPEED** is m/s. METERS PER SECOND. *eg. 20 m/s, 43 m/s*.

Other Units we **SHOULD** use:

**Weight = N (Newtons)**

**Mass = KG (Kilograms)**

**Energy = J (Joules)**

**REMEMBER**: **ALWAYS** put these at the **end** of your answers on a test paper! *Marks could be lost* :'(
