circular motion conceptual

Front

What force keeps satellites in orbit around the Earth?

Back

Gravity provides the centripetal force that keeps satellites in orbit.

Front

What is the term for the circular motion of the Earth around its internal axis?

Back

Rotation is the type of circular motion of the Earth around its internal axis.

Front

What is the formula for velocity in uniform circular motion?

Back

The velocity (v) in uniform circular motion is given by v = 2πr/T, where r is the radius and T is the period.

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

Front

How is centripetal acceleration calculated?

Back

Centripetal acceleration (a_c) is calculated using the formula a_c = v²/r, where v is the velocity and r is the radius of the circular path.

Front

What is the relationship between centripetal force and mass?

Back

Centripetal force (F_c) is directly proportional to the mass (m) of the object and its centripetal acceleration (a_c), given by F_c = m * a_c.

Front

What is the formula for centripetal force?

Back

The formula for centripetal force is F_c = m * v²/r, where m is the mass, v is the velocity, and r is the radius.

Front

What happens to centripetal force if the radius of the circular path is doubled?

Back

If the radius is doubled, the centripetal force required for the same mass and velocity is halved.

Front

What is the effect of increasing the speed of an object in circular motion on the centripetal force required?

Back

Increasing the speed of an object in circular motion increases the centripetal force required to maintain that motion.

Front

What is the direction of centripetal force in circular motion?

Back

The direction of centripetal force is always towards the center of the circular path.
