1. The tyres of cars are broader than the tyres of bikes. Why?
2. Explain pressure with an example.
3. How can you increase or decrease pressure acting on a body?
4. What are the effects of forces on area of contact of the surface?
5. List out some advantages of pressure.
Answers
Answer:
1. The tyres of a car carries heavy weight than that of bike. Border tyres are for decreasing the pressure.
2. Pressure- When the force of an object depend upon area. eg. when we are carrying bag with thin stripes it excert a large amount of force in our shoulders. Here it depends upon area so we can call it as pressure.
3. By increasing the surface area we can decrease the pressure and by decreasing the surface area we can increase the pressure.
4. It can change the shape of an object.
5. It can help us with our day to day activities.
