• Friction

What type of force tends to slow you down as you are swimming?

• Gravity

Forces are not things we can see. But we can often tell when a force is acting.

            We know a force must be acting if we observe a:

• change in the shape of an object.

• change in the colour of an object.

• change in the temperature of an object.

• new substance being formed.
