What is centripetal acceleration?

Back

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

Front

Why is centripetal acceleration present in circular motion?

Back

Centripetal acceleration is present in circular motion due to the change in direction of the object's velocity as it moves along the circular path.

Front

What is the formula for centripetal acceleration?

Back

The formula for centripetal acceleration (a_c) is a_c = v^2 / r, where v is the tangential speed and r is the radius of the circular path.

Front

What does 'change in velocity' refer to in the context of circular motion?

Back

In circular motion, 'change in velocity' refers to the continuous change in the direction of the velocity vector, even if the speed remains constant.

Front

What is tangential velocity?

Back

Tangential velocity is the linear speed of an object moving along a circular path, measured at any point along the path.

Front

How does tangential velocity relate to centripetal acceleration?

Back

Tangential velocity is used in the formula for centripetal acceleration; as tangential velocity increases, centripetal acceleration increases if the radius remains constant.

Front

What is the relationship between radius and centripetal acceleration?

Back

Centripetal acceleration is inversely proportional to the radius; as the radius increases, the centripetal acceleration decreases for a constant tangential speed.

Front

What happens to centripetal acceleration if the speed of the object increases?

Back

If the speed of the object increases while moving in a circular path, the centripetal acceleration increases.

Front

Can an object have centripetal acceleration without changing speed?

Back

Yes, an object can have centripetal acceleration without changing speed, as the acceleration is due to the change in direction of the velocity vector.

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed along a circular path.
