Roller Coaster Physics Quiz

What is the primary goal of the roller coaster problem discussed in the video?

• To measure the length of the track

• To calculate the height of the roller coaster

• To determine the velocities at points B, C, and D

• To find the mass of the roller coaster car

Which theorem is used to solve for the velocities in the roller coaster problem?

• Pythagorean Theorem

• Work-Energy Theorem

• Conservation of Momentum

• Newton's Second Law

What force is primarily responsible for doing work on the roller coaster cart?

• Friction

• Normal force

• Air resistance

• Gravity

What is the total mechanical energy at point A primarily composed of?

• Kinetic energy

• Gravitational potential energy

• Thermal energy

• Elastic potential energy

Why is the total mechanical energy at point A important?

• It is used to measure the height of the loop

• It remains constant and helps find velocities at other points

• It determines the length of the track

• It helps in calculating the mass of the cart

What is the velocity of the roller coaster cart at point B?

• 14 meters per second

• 24.3 meters per second

• 30 meters per second

• 19.8 meters per second

At point C, what type of energy does the roller coaster cart have?

• Only kinetic energy

• Only potential energy

• Both kinetic and potential energy

• No energy

What happens to the roller coaster cart's mechanical energy when brakes are applied?

• It is converted into potential energy

• It is converted into kinetic energy

• It is converted into heat

• It remains unchanged

Why is it important to have a mathematical limit for the height of the roller coaster loop?

• To prevent people from falling out

• To reduce the cost of construction

• To increase the thrill of the ride

• To ensure the cart moves faster

What role do brakes play in the roller coaster system?

• They convert mechanical energy into heat to stop the cart

• They act as a conservative force

• They increase the speed of the cart

• They maintain the cart's velocity
