What is the advantages and disadvantages of friction?
Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches.
What are the advantages of friction force?
Advantages of friction:
- Friction enables us to walk freely.
- It helps to support ladder against wall.
- It becomes possible to transfer one form of energy to another.
- Objects can be piled up without slipping.
- Breaks of vehicles work due to friction.
- It always resists the motion, so extra energy is required to overcome it.
What are the advantages and disadvantages of friction?
Friction also encourages surface air masses to merge and rise, which helps the rain cycle. Rough terrain, trees, and buildings create friction that acts on wind speed. 3-The friction between the animals’ feet and the ground makes running and walking easier. In fact, without friction, the animals would have difficulty standing.
Why does friction slow down a moving object?
Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.
How does friction help in the transfer of energy?
In mechanical engineering, the friction between parts in a machine helps in the transfer of energy. Without friction, the parts will slip and there won’t be any solid contact established to transfer energy. Friction helps in making fire
What are some examples of friction in life?
7-Forest fires are due to friction between the branches of the trees. 8-Extra friction makes it difficult to move an object, such as sliding a box across the ground or walking in deep snow. 9-Any device that has moving parts can quickly wear out due to friction.
