Why do we need to start pedaling in a low gear when riding a bike?

• To decrease the speed

• To go faster

• To increase the torque

• To make it easier to pedal

What do we do when driving up a hill in a car?

• Start in a low gear and work our way up

• Change to neutral gear

• Stay in the same gear

• Start in a high gear and work our way down

What is the purpose of a flywheel in a car?

• To store and release energy to maintain a constant speed

• To increase the speed of the car

• To decrease the torque of the engine

• To provide additional power for acceleration

How does using a smaller gear ratio affect the torque in a vehicle?

• It increases the torque
