Question

Provide at least two negative effects of friction, and

explain how friction can be reduced.
PROUDTS

Answer 1

Sample Response: Friction can cause overheating in parts that rub together. It can also cause these parts to wear out. Polish, oil, and nonstick surfaces can decrease friction to make moving parts last longer and prevent overheating.

Step-by-step explanation:

Answer 2

Friction can lead to heat generation and wear and tear. It can be reduced by lubrication and using smoother surfaces.

Step-by-step explanation:

Negative Effects of Friction:

1. Heat generation: Friction between two surfaces can result in the generation of heat, leading to wastage of energy. This can cause damage to machinery or even start fires in extreme cases.

2. Wear and tear: Friction can cause wear and tear on surfaces in contact, leading to the deterioration of materials over time.

Reducing Friction:

1. Lubrication: Applying a lubricant, such as oil or grease, between surfaces can help reduce friction and minimize wear and tear.

2. Smooth surfaces: Creating smoother surfaces on objects can decrease the amount of friction between them.
