Centripetal force is the force that keeps an object moving in a circular path. Centripetal force always acts in the direction of the center of the circle. Centripetal force is a real physical force that pulls objects radially inward. Centripetal force is necessary to maintain circular motion.
Sure! What are the following statements about centripetal force you would like to know if they are true or not?
No, projectiles are not always affected by centripetal force. Centripetal force only comes into play when there is circular motion involved. In the case of projectiles, the force of gravity is the dominant force acting on the object.

Yes true. But they need not be got cancelled though their resultant is zero.

Centripetal force is a force that is required to exist to have a circular motion. Thus the centripetal force can be any force that is able to accomplish this task. Examples of centripetal forces are the gravitational force, the electromagnetic force, the frictional force, or the constraint forces. The centripetal force depends on the system that is involved in be in a spin of a rigid body, or of a planetary motion, etc. Each particular system that requires a rotation or a spin needs to have a corresponding centripetal force.
true
true
Yes. That follows from Newton's Second Law: without a centripetal force, there could be no centripetal acceleration. Since the car accelerates towards the center of the circle, it follows that there must be a force that causes this acceleration.
true
Actually, the force that keeps objects moving in a circle is called centripetal force. It acts towards the center of the circle and is necessary to counteract the outward centrifugal force that would otherwise cause the object to move in a straight line.
Yes, the statement is true. Centripetal force is a force that acts towards the center of a circular path and is responsible for changing an object's direction, rather than its speed. It keeps an object moving in a circular path by constantly pulling it towards the center of the circle.
