Centripetal acceleration

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration of an object moving in a circular path, directed towards the center of the circle.

Front

What is the formula for centripetal acceleration?

Back

The formula for centripetal acceleration (a_c) is a_c = v²/r, where v is the velocity and r is the radius of the circular path.

Front

What is the direction of centripetal acceleration?

Back

Centripetal acceleration is always directed towards the center of the circular path.

Front

What is the relationship between speed and centripetal acceleration?

Back

As the speed of an object increases, the centripetal acceleration increases, provided the radius remains constant.

Front

What happens to centripetal acceleration if the radius of the circular path increases?

Back

If the radius increases while speed remains constant, the centripetal acceleration decreases.

Front

What is the role of centripetal force in circular motion?

Back

Centripetal force is the net force that acts on an object moving in a circular path, directed towards the center, and is responsible for maintaining circular motion.

Front

What is an example of centripetal force in action?

Back

An example of centripetal force is the tension in a string when a ball is swung in a circle.

Front

How does mass affect centripetal acceleration?

Back

Mass does not directly affect centripetal acceleration; however, it affects the centripetal force required to maintain circular motion.

Front

What is the centripetal acceleration of an object moving at 10 m/s in a circle with a radius of 5 m?

Back

Using the formula a_c = v²/r, the centripetal acceleration is 20 m/s².

Front

What is the centripetal acceleration of an object moving at 4 m/s in a circle with a radius of 2 m?

Back

Using the formula a_c = v²/r, the centripetal acceleration is 8 m/s².
