Uniform Circular Motion CFU

Front

What is Uniform Circular Motion?

Back

Uniform Circular Motion is the motion of an object traveling at a constant speed in a circular path. The direction of the velocity vector changes continuously, resulting in acceleration.

Front

Does an object in Uniform Circular Motion have acceleration?

Back

Yes, an object in Uniform Circular Motion has acceleration directed towards the center of the circle, known as centripetal acceleration.

Front

What is centripetal force?

Back

Centripetal force is the net force acting on an object moving in a circular path, directed towards the center of the circle.

Front

What happens to an object in circular motion when it is released?

Back

An object in circular motion will fly out tangent (straight line) to the circular path when released.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) is given by the formula a_c = v^2 / r, where v is the velocity and r is the radius of the circular path.

Front

What is the relationship between velocity and radius in circular motion?

Back

In uniform circular motion, the velocity of the object is directly proportional to the radius of the circle and inversely proportional to the time period of rotation.

Front

How do you calculate the maximum velocity of an object at the top of a hill in circular motion?

Back

The maximum velocity (v) can be calculated using the formula v = √(g * r), where g is the acceleration due to gravity and r is the radius of curvature.

Front

What is the direction of centripetal force at the top of a loop?

Back

The direction of centripetal force at the top of a loop is towards the ground.

Front

If a stopper takes 0.2 seconds to make a complete circle with a radius of 0.3 meters, how do you find its velocity?

Back

Velocity (v) can be calculated using the formula v = 2πr / T, where r is the radius and T is the time period.

Front

What is the formula for calculating the period of circular motion?

Back

The period (T) of circular motion is the time taken to complete one full revolution, calculated as T = 1/f, where f is the frequency.
