Which simple machine is used to reduce friction between moving parts in a vehicle?
easy Q3 of 15
Step-by-Step Solution
Step 1: Understand the role of wheel and axle
Wheel and axle reduce friction by allowing smooth rotation, making it easier for vehicles to move.Step 2: Analyze other options
Lever is for lifting loads, pulley changes force direction, wedge splits objects; none reduce friction in vehicles.Final Answer:
Wheel and Axle → Option AQuick Check:
Reducing friction in vehicles = Wheel and Axle ✅
Quick Trick: Wheels reduce friction by rolling instead of sliding.
Common Mistakes:
MISTAKES- Confusing lever or pulley with wheel and axle in vehicles.
