Vertical Circular Motion Quiz

What is the direction of the centripetal force in a circular motion?

• Outwards the circular motion

• Inwards the circular motion

• Tangent to the circular motion

• Perpendicular to the plane of motion

At the top of a vertical circular motion, what forces act on the object?

• Only tension

• Tension and gravitational force

• Only centripetal force

• Only gravitational force

What is the net force acting on an object in vertical circular motion at the bottom of the path?

• Fc = W - T

• Fc = T

• Fc = T - W

• Fc = T + W

Why does water stay inside the bucket when it is swung in a vertical circular motion?

• Inertia and Gravitational force

• Centripetal force

• Normal force

• Inertia and Centripetal force

Which of the following are real-life examples of vertical circular motion? (Select all that apply)

• A Ferris wheel

• A bucket of water being swung in a vertical circle

• A spinning top on a table

• Earth's orbit around the Sun

What is the requirement for an object to achieve the minimum velocity needed to stay in vertical circular motion at the top of the path?

• The rope must have maximum tension.

• The rope must have zero tension.

• The centripetal force must be greater than the gravitational force.

• The speed must be constant.

If only tension and gravitational force are acting on an object, what is the formula to calculate the minimum velocity required to keep the object in vertical circular motion at the top of its path?

• v_min = sqrt(2*g*r)

• v_min = sqrt(g/r)

• v_min = g*r

• v_min = sqrt(g*r)
