Step-by-step solution for: Friction Worksheets
Let's solve each question from the worksheet about friction, based on the provided information and scientific understanding.
---
Answer:
Friction slows down or stops a moving object. When two surfaces rub together, friction acts in the opposite direction of motion, reducing the speed of the object. For example, when you ride a bike and apply brakes, friction between the brake pads and the wheel slows the bike down.
Explanation:
Friction is a resistive force that opposes motion. It converts kinetic energy into heat, which causes the object to lose speed over time unless another force (like pushing) keeps it moving.

Answer:
It is easier to walk on the sidewalk than on ice.
Explanation:
The sidewalk has a rougher surface, which creates more friction between your shoes and the ground. This friction helps you push off the ground without slipping. Ice is smooth and slippery, so there is very little friction, making it hard to walk without sliding.
---
Answer:
Friction is important because it allows us to move, grip objects, stop vehicles, and perform many everyday activities safely.
Explanation:
Without friction, we couldn’t walk (our feet would slip), cars couldn’t stop (brakes wouldn’t work), and we couldn’t hold things (they’d slide out of our hands). Friction enables control and stability in motion.

Answer:
1. Walking: Friction between your shoes and the ground lets you walk without slipping.
2. Brakes in cars and bikes: Friction between brake pads and wheels slows or stops the vehicle.
3. Writing with a pencil: Friction between the pencil lead and paper allows marks to be made.

Answer:
You could make a slide ride faster by making the slide surface smoother or using a lubricant like water or oil.
Explanation:
A smoother surface reduces friction between the person and the slide. Less friction means less resistance, so the person can slide down faster. Adding water also reduces friction by creating a slippery layer.
---
Answer:
You could make a slide ride slower by making the surface rougher or adding materials like sandpaper or carpet.
Explanation:
A rougher surface increases friction, which slows down the person sliding. More friction means more resistance, so the slide becomes slower and safer for younger children.
---
✔ Summary:
Friction is essential in daily life—it helps us move, stop, and interact with objects. Understanding how to increase or decrease friction helps us design safer and more efficient tools and environments.

1. What does friction do to an object that is moving?
Answer:
Friction slows down or stops a moving object. When two surfaces rub together, friction acts in the opposite direction of motion, reducing the speed of the object. For example, when you ride a bike and apply brakes, friction between the brake pads and the wheel slows the bike down.
Explanation:
Friction is a resistive force that opposes motion. It converts kinetic energy into heat, which causes the object to lose speed over time unless another force (like pushing) keeps it moving.
