In this activity, we will be learning about air resistance.

Air resistance is the force of the air pushing against objects.

It might be the wind blowing against a tree or it might be caused by the object, like a lorry, moving through the air.

Another example of this is that when a plane flies through the air, the air particles resist the aeroplane, making it harder for the aeroplane to move.

Think about how easily air is pushed out of the way by an object and how big the force of air resistance might be, pushing against the object - even though air is invisible!

Now it's time to try some questions about air resistance yourself.
