Worked Solution & Example Answer:Physics is central to the functioning of many of the pieces of equipment in a children’s playground - Junior Cycle Science - Question (b) - 2018
Step 1
What is friction?
Answer
Friction is defined as a force that opposes motion between two surfaces in contact. It acts when an object moves or attempts to move along another surface, slowing down its movement. Friction is essential for controlling motion and ensuring safety, such as when a child climbs or slides.
Step 2
What could happen to a child going down a slide if there was too much friction?
Answer
If there is too much friction while going down a slide, several outcomes may occur:
- The child may move more slowly, leading to a less enjoyable experience.
- The child could stop sliding altogether, which may cause frustration or lead to the risk of falling back.
- Excessive friction may even result in burns or discomfort due to the increased interaction between the skin and the slide's surface.
Step 3
Why might a child go down a slide in a waterpark at a faster speed than a slide in a playground?
Answer
A child may go down a slide in a waterpark at a faster speed due to several factors:
- Water provides lubrication, reducing friction between the child and the slide.
- Water slides are often designed with a steeper incline compared to typical playground slides.
- The presence of water can enhance the overall sliding experience, allowing for a smoother and quicker descent.
