Centripetal Force on a Car Moving in a Circular Path
When a car moves in a circular path, it experiences a force that acts towards the center of the circle. This force is called the centripetal force. In the absence of this force, the car would continue to move in a straight line. The centripetal force is responsible for keeping the car moving in a circular path.
Calculation of Centripetal Force
The centripetal force on the car is given by the formula:
Fc = (mv2)/r
where Fc is the centripetal force, m is the mass of the car, v is the speed of the car and r is the radius of the circular path.
Substituting the given values we get:
Fc = (1000 kg) x (10 m/s)2 / 10 m = 10000 N
Source of Centripetal Force
The centripetal force required to keep the car moving in a circular path is provided by the frictional force between the tires of the car and the road. The frictional force acts towards the center of the circle and is responsible for providing the required centripetal force.
Thus, in the case of a car moving in a circular path, the required centripetal force is provided by the frictional force between the tires of the car and the road. The magnitude of the centripetal force is given by the formula Fc = (mv2)/r.
