Correct Answer - Option 1 : B
The correct answer is Centripetal.
-
Centrifugal force refers to moving away from the centre point.
- The centrifugal force is an inertial force also known as fictitious force or pseudo force which acts on all objects when viewed in a rotating frame of reference.
- Some examples of Centrifugal force are Vehicle driving around a curve, Weight of an object at the poles and on the equator, rotation of the earth, stone on a string, etc.
-
Centripetal force refers to the net force that acts on an object to keep it moving along a circular path.
- The unit of centripetal force is Newton.
- Some examples of Centripetal force are spinning a ball on a string or twirling a lasso, Planets orbiting around the sun, Going through a loop on a roller coaster, and turning a car.
-
Gravitational Force is always attractive in nature and the gravitational force of the Earth is equal to the force the Earth exerts on individuals.
- The gravitational force at rest, on or near the surface of the Earth is equal to the weight of the Individual.
-
The normal force is the support force exerted upon an object that is in contact with another stable object.
- Example: If a toy is resting upon a surface, then the surface is exerting an upward force upon the toy to support the weight of the toy.
