A common example of friciton is when a bike stops. When the brakes are applied the friction on the pads cause the bike to stop.
<span>At an instant when the displacement is equal to a/2,
Potential energy U = 1/2ka(square) where a is displacement.
when a= a/2
U = 1/4ka(square)
U = E/4
Potential Energy = 1/4 Total energy</span>
