Cyclist Dynamics and Forces

The video tutorial explores uniform circular motion, focusing on centripetal force and its effects. It discusses the role of banked tracks and friction in maintaining stability. The tutorial uses a cyclist as an example to explain how banking helps maintain balance without a banked track. It covers resolving forces and angles, using trigonometry to calculate the angle of inclination necessary for stability.

What is the primary force acting on an object in uniform circular motion?

• Centripetal force

• Magnetic force

• Frictional force

• Gravitational force

What challenge does a cyclist face when there is no banked track?

• Lack of air resistance

• Insufficient friction on the wheels

• Excessive gravitational pull

• Too much centripetal force

In the absence of a banked track, what does a cyclist mimic to maintain balance?

• A horizontal line

• A straight path

• A banked track

• A vertical climb

How does a cyclist maintain stability while turning at high speeds?

• By using a heavier bike

• By reducing weight

• By banking their body

• By increasing speed

What is the role of friction when a cyclist is banking?

• To reduce air resistance

• To provide centripetal force

• To increase speed

• To balance gravitational force

What happens if the resultant force does not align with the cyclist?

• The cyclist remains stable

• The cyclist falls over

• The cyclist slows down

• The cyclist speeds up

What is the normal force's role in maintaining a cyclist's vertical stability?

• It increases the cyclist's speed

• It reduces friction

• It counteracts gravitational force

• It acts parallel to the ground

What trigonometric function relates the friction and normal forces in the context of banking?

• Sine

• Cosine

• Tangent

• Cotangent

How is the angle of inclination calculated for a cyclist banking on a turn?

• Using sine function

• Using cosine function

• Using secant function

• Using tangent function

What does the angle theta represent in the context of a cyclist banking?

• The inclination from the vertical

• The weight of the cyclist

• The distance of the turn

• The speed of the cyclist
