¿Qué es la fricción?

The video explains how friction affects the movement of objects, particularly cars on icy roads. Friction is a force that acts in the opposite direction of motion, slowing down moving objects. The amount of friction depends on the surface type; smooth surfaces have less friction, while rough surfaces have more. Ice on roads reduces friction, increasing the likelihood of skidding.

What is the primary reason a car skids on an icy road?

• Reduced friction

• Excessive speed

• Increased gravitational pull

• Lack of air resistance

How does friction act in relation to an object's motion?

• In the same direction

• In the opposite direction

• Perpendicular to the motion

• It does not affect motion

What happens to a moving object when friction is applied?

• It speeds up

• It slows down

• It remains unaffected

• It changes direction

Why do skaters slide easily on an ice rink?

• Due to air resistance

• Because of gravity

• Due to low friction

• Because of high friction

What type of surface creates more friction?

• Smooth surfaces

• Rough surfaces

• Wet surfaces

• Icy surfaces
