Gears | MCQs

Explanation

Gears can:

• Change speed: Gears can increase or decrease
• Change direction: Gears can change the direction of rotation
• Change force: Gears can increase or decrease the force

However, gears cannot change the fulcrum, which is the pivot point or axis of rotation.

Explanation

• A gear (cog) is a toothed wheel that meshes with other gears to transmit rotational motion or change the direction of force.
• The pointed edges like teeth are used to engage with other gears and transmit power.
