Circular Motion Quiz

What is the condition required for circular motion?

• The force must be acting in the same direction as the velocity

• The force must be acting opposite to the velocity

• The force must be acting at a right angle to the velocity

• The force must be acting parallel to the velocity

What is the term for the force that keeps an object in circular motion?

• Centrifugal force

• Centripetal force

• Frictional force

• Gravitational force

What happens to the velocity of an object in circular motion if the centripetal force is removed?

• The velocity increases

• The velocity decreases

• The velocity remains the same

• The velocity becomes zero

What is the equation for centripetal force?

• F = mv

• F = ma

• F = mv^2/r

• F = ma^2

What is the angular velocity of an object in circular motion?

• The speed of the object

• The distance traveled by the object

• The rate of change of velocity

• The rate of change of angle

What is the formula for speed in circular motion?

• Speed = distance / time

• Speed = time / distance

• Speed = 2πr / T

• Speed = 2πr / frequency

What is the formula for finding the speed of a plane in circular motion?

• Speed = √(GR / tanθ)

• Speed = √(GR * tanθ)

• Speed = √(GR + tanθ)

• Speed = √(GR - tanθ)

What happens to the support force in vertical circular motion?

• It remains the same throughout

• It increases at the top and decreases at the bottom

• It decreases at the top and increases at the bottom

• It is zero at the top and maximum at the bottom

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

• T = 2πr / v

• T = v / 2πr

• T = 2πr / a

• T = a / 2πr

What is the formula for the acceleration in circular motion?

• a = v^2 / r

• a = r / v^2

• a = v / r^2

• a = r^2 / v
