Physics Concepts from the London Eye

What is the initial weight of the tourist entering the London Eye?

• 650 Newtons

• 600 Newtons

• 500 Newtons

• 700 Newtons

At time T=0, what is the relationship between the resultant force and the centripetal force?

• Resultant force is greater than centripetal force

• Resultant force is less than centripetal force

• Resultant force equals centripetal force

• Resultant force is zero

Why is a horizontal force necessary for the tourist on the London Eye?

• To decrease the friction

• To provide a force towards the center of rotation

• To balance the weight of the tourist

• To increase the speed of rotation

What provides the horizontal component necessary for centripetal motion?

• Gravity

• Magnetic force

• Air resistance

• Friction

How does the horizontal force vary during the ride?

• It varies sinusoidally

• It remains constant

• It decreases exponentially

• It increases linearly

At what point is the horizontal force F equal to -0.050 Newtons?

• At the midpoint of the ride

• At the start of the ride

• At the top of the ride

• At the bottom of the ride

What is the magnitude of the force F when the pod is 40 degrees above the horizontal?

• 0.045 Newtons

• 0.048 Newtons

• 0.050 Newtons

• 0.038 Newtons

Which trigonometric function is used to calculate the force F at 40 degrees?

• Sine

• Cosine

• Tangent

• Cotangent

What is the calculated distance D of the center of mass from the center of rotation?

• 70 meters

• 55 meters

• 50 meters

• 62 meters

What is the formula used to calculate the distance D?

• Force = mass x distance squared / time

• Force = mass x angular velocity squared x distance

• Force = mass x velocity squared / radius

• Force = mass x acceleration
