BICYCLES

BIKE FORCES

• Friction acts on the bike when the brake is used. Friction is an unbalanced force
• Gravity acts on it by keeping the bike on the ground. Gravity is a force that works at a distance, and it is a balanced force
• You push the pedals to accelerate. The push is unbalanced a force

SIMPLE MACHINES

• There is wheel and axle for the wheels of the bike.
• A wedge is used when you pull the brake handle and the foam pushes against the wheel
• The chain of the bike is a pulley.
• When you need to raise or lower the bike seat, there is a screw.
• The handle bars move the wheel around a fulcrum, so it is a lever.
