Uniform Circular Motion

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.

Front

What is the direction of velocity in Uniform Circular Motion?

Back

The direction of velocity is tangential to the circular path at any point.

Front

What is the direction of acceleration in Uniform Circular Motion?

Back

The acceleration is directed towards the center of the circular path.

Front

What is centripetal force?

Back

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

Front

What is the formula for centripetal acceleration?

Back

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

Front

How does speed relate to radius in Uniform Circular Motion?

Back

For a given centripetal acceleration, an increase in radius results in a decrease in speed.

Front

What happens to the net force if the speed of an object in circular motion increases?

Back

If the speed increases, the net force must also increase to maintain circular motion.

Front

What is the relationship between period and frequency in circular motion?

Back

Period (T) is the time taken for one complete revolution, while frequency (f) is the number of revolutions per unit time; f = 1/T.

Front

What is the formula for the speed of an object in circular motion?

Back

Speed (v) = 2πr / T, where r is the radius and T is the period.

Front

What is the effect of mass on centripetal force?

Back

Centripetal force is directly proportional to the mass of the object; F_c = m * a_c.
