Question

Give 2 examples to support that friction leads to wastage of energy

Answer 1

friction also leads to wastage of energy .
1..when we walk on a ground or on a rough surface then friction is applied and we tired of walking .
2..Friction is applied on an machine and it causes wastage of energy .
Thus we can say that friction also leads to wastage of energy.

Answer 2

Answer

Friction leads in the wastage of energy as follows -

1. When we walk on a road the friction applies it force and thus we are tired and it consumes our energy

2. When of friction is applied on a machine then it consumes more energy and thus friction consumes more energy
