Vertical Circular Motion Concepts

The video tutorial explains vertical circular motion by solving a problem involving a 2 kg stone swung in a circle. It covers the forces acting on the stone, such as gravity and centrifugal force, and analyzes tension at different points in the circle. The tutorial calculates the maximum speed the stone can achieve without exceeding the string's tension limit. Key learnings include understanding the forces in circular motion and calculating maximum speed based on tension constraints.

What is the mass of the stone used in the vertical circular motion problem?

• 1 kg

• 2 kg

• 3 kg

• 4 kg

What is the length of the string in the vertical circular motion problem?

• 2 m

• 4 m

• 3 m

• 1 m

In vertical circular motion, what force acts downward on the body?

• Magnetic force

• Frictional force

• Centrifugal force

• Gravitational force

What happens to the potential energy of the body as it moves upward in vertical circular motion?

• It remains constant

• It decreases

• It increases

• It becomes zero

At which point in the vertical circle is the tension in the string maximum?

• Topmost point

• Bottommost point

• Any point

• Midpoint

Why is the tension at the bottommost point greater than at other points?

• Because the velocity is minimum

• Because the velocity is maximum

• Because the potential energy is maximum

• Because the centrifugal force is zero

What is the maximum tension the string can withstand in the problem?

• 100.6 N

• 120.6 N

• 140.6 N

• 160.6 N

What is the calculated maximum speed of the stone in m/s?

• 11 m/s

• 44 m/s

• 22 m/s

• 33 m/s

What is the significance of the bottommost point in vertical circular motion?

• It has maximum tension

• It has minimum tension

• It has zero velocity

• It has maximum potential energy

What should be considered when designing a system for vertical circular motion?

• The system should withstand maximum tension

• The initial velocity should be zero

• The mass should be light

• The string should be short
