Y5/6 Water and Air Resistance Unit Quiz

What is air resistance?

• A force that acts between a moving object and the air molecules around it, slowing the object down

• A force that acts between a moving object and the water molecules around it, slowing the object down

• A force that acts between a stationary object and the air molecules around it, speeding the object up

• A force that acts between a stationary object and the water molecules around it, speeding the object up
