Understanding Circular Motion and Forces

What is the mass of the bucket used in the vertical circle experiment?

• 1 kg

• 4 kg

• 2 kg

• 3 kg

What is the constant speed at which the bucket is swung in the circle?

• 2 m/s

• 3 m/s

• 4 m/s

• 5 m/s

Which formula is used to calculate the centripetal force in this scenario?

• mass times velocity

• force times distance

• mass times velocity squared over radius

• mass times acceleration

What is the calculated centripetal force acting on the bucket?

• 40 N

• 32 N

• 24 N

• 16 N

At the lowest point, what two forces contribute to the net force on the bucket?

• Tension and friction

• Gravity and air resistance

• Tension and gravity

• Centripetal force and tension

What is the tension in the string when the bucket is at its lowest point?

• 40 N

• 32 N

• 60 N

• 51.6 N

At the highest point, in which direction does the tension in the string act?

• Horizontally

• Downward

• No tension at the top

• Upward

What is the tension in the string when the bucket is at the top of the circle?

• 10 N

• 12.4 N

• 15 N

• 18 N

Why is it important to understand centripetal force as a net force?

• It combines multiple forces acting on an object

• It is the only force acting on an object

• It is always equal to tension

• It simplifies calculations

What should be considered when dealing with competing forces in circular motion?

• Only the largest force

• The direction of motion

• The net force and its components

• The speed of the object
