Question

define centripetal force with example????​

Answer 1

it is a force which is required for a body to move in a circular path called centripetal force . eg rotation of tyre , etc.

Answer 2

$\blue{\large{\mathcal{\underline{\underline{Answer :-}}}}}$

Centripetal force is the component of force acting on an object in curvilinear motion which is directed toward the axis of rotation or centre of curvature.

The unit of centripetal force is Newton.

The centripetal force is always directed perpendicular to the direction of the displacement of the object. If an object accelerates according to the changes of velocity, then it can change either its speed or direction of motion. In simple terms, if any moving object in a circular path is constantly changing its direction means it is constantly accelerating. Using Newton’s second law of motion, if an object is travelling in a circular path, it is found that the centripetal force of an object moving in a circular path always acts towards the centre of the circle.

Some Examples Of Centripetal Force

• Spinning a ball on a string or twirling a lasso: Here the centripetal force is provided by the force of tension on the rope pulls the object in toward the centre.

• Turning a car: Here the centripetal force is provided by the frictional force between the ground and the wheels.

• Going through a loop on a roller coaster: The force is provided by the Normal Force as the seat or wall pushes you toward the centre.

• Planets orbiting around the Sun: Centripetal Force is provided by Gravity.
