write example of static and kinetic friction?
Answers
Answer:
A parked car is an example for static friction and moving car is the example for kinetic friction
Answer:
Static friction is a resistive force that keeps an object at rest. In other words, it is the frictional force between a stationary object and the sliding surface. If the object is moving then we call the friction kinetic friction. We encounter static friction quite often in our life, let’s find out with some real-life examples.
Static friction
Static friction (top) and kinetic friction (below)
You might have tried pushing some heavy objects. Initially, for a few seconds, they would not move, the friction involved here is static friction. But after some time you get enough force to overcome the static friction and push the object forward. When the object moves kinetic friction comes into action.
In the example, you might have understood that static friction is always greater than kinetic friction. Static friction is generally denoted by fs and kinetic friction as fk.
The value of static friction varies between zero to the maximum force required to move the object(limiting friction).
