The amount of air or water resistance changes how fast things move. Find out more in this KS2 primary Bitesize science guide. read more
Friction occurs when objects move through water or air. Air resistance is a type of friction between air and another material. For example, when an aeroplane flies through the air, air particles hit the aeroplane making it more difficult for it to move through the air. read more
Ice-skating also demonstrates friction, with the edge of the blades as the centre of gravity. Air resistance or drag, acts against gravity on falling objects and this is how parachutes work. Swimmers also use water resistance to help them move forward. read more
