Answer: You use friction when your bike stops.
Explanation: Force and friction affect our daily lives in numerous amounts of ways. For instance, when a football is kicked, it moves faster later after some time its force decreases due to friction. 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>Work equals
force times distance. When you move an object, you are exerting a force onto
it. By exerting a force on the object, you are actually displacing it from its
initial position. You cannot apply force to the object without altering its
position. Keep in mind that when you exert work, you are exerting energy too. So
the work must have a unit in joules in SI units. Force is in newtons or
kilogram meter per second squared. And distance is in meters. So you will have
newton-meter or joules. </span>
