Centripetal acceleration is the acceleration towards the center of a circular motion. It is always directed towards the center and perpendicular to the velocity of the object.
Centripetal acceleration can be calculated using the formula a = v^2/r, where a is the acceleration, v is the velocity, and r is the radius of the circular motion.
Centripetal acceleration is caused by the centripetal force, which is the force that keeps an object moving in a circular motion. This force can come from various sources, such as tension, gravity, or friction.
No, centripetal acceleration is not constant. As an object moves in a circular motion, its velocity and direction are constantly changing, which means the centripetal acceleration is also changing.
Centripetal acceleration and centripetal force are directly related. As the centripetal force increases, the centripetal acceleration also increases, and vice versa. This relationship is described by Newton's second law of motion, F = ma.
