Which force acts downwards on a paper plane due to Earth's pull?

• Lift

• Thrust

• Drag

• Gravity

Which force helps a paper plane to stay in the air and counteracts gravity?

• Drag

• Lift

• Thrust

• Friction

What is the main purpose of thrust in a paper plane flight?

• To slow the plane down

• To keep the plane balanced

• To move the plane forward

• To make the plane spin

Which force acts in the opposite direction to the movement of the paper plane, slowing it down?

• Lift

• Gravity

• Drag

• Thrust

If you want your paper plane to travel further, which force should you try to minimise?

• Lift

• Gravity

• Drag

• Thrust

Which of the following is NOT a force acting on a paper plane?

• Gravity

• Lift

• Magnetism

• Thrust

What could you change in your paper plane design to increase lift?

• Make the wings larger

• Use heavier paper

• Add more folds to the nose

• Make the plane shorter
