What is the principle of conservation of energy?

• Energy cannot be created or destroyed; it can only be transferred or transformed from one form to another
• Energy can be created or destroyed; it is not conserved
• Energy can be converted into matter
• Energy can only be transferred between systems of equal temperature
• Energy can only be transformed into thermal energy

How does friction affect the mechanical energy of an object?

• Friction can cause a loss of mechanical energy, resulting in a decrease in the object's speed or height
• Friction increases the mechanical energy of an object
• Friction has no effect on the mechanical energy of an object
• Friction converts mechanical energy into thermal energy
• Friction converts mechanical energy into potential energy

How do height, steepness, curvature, and resistance affect the design and performance of a roller coaster?

• Height affects the potential energy, steepness affects the speed, curvature creates the sensation of weightlessness, and resistance affects the speed
• Height affects the speed, steepness affects the potential energy, curvature affects the resistance, and resistance affects the design
• Height affects the resistance, steepness affects the curvature, curvature affects the potential energy, and resistance affects the speed
• Height affects the design, steepness affects the resistance, curvature affects the speed, and resistance affects the potential energy
• Height affects the potential energy, steepness affects the resistance, curvature affects the speed, and resistance affects the design

What happens to potential energy as an object moves downward on a roller coaster track?

• Potential energy is converted into kinetic energy
• Potential energy is converted into thermal energy
• Potential energy remains constant
• Potential energy increases
• Potential energy decreases

How does the steepness of a roller coaster track affect the speed of the ride?

• A steeper track results in a faster ride
• A steeper track results in a slower ride
• The steepness of the track has no effect on the speed
• The speed is independent of the track's steepness
• The speed is determined solely by the height of the track

What is the role of curvature in the design of a roller coaster track?

• Curvature can create the sensation of weightlessness
• Curvature increases the resistance on the ride
• Curvature decreases the potential energy
• Curvature has no effect on the design
• Curvature reduces the speed of the ride

How does resistance, such as air resistance, affect the performance of a roller coaster?

• Resistance can decrease the speed of the ride
• Resistance has no effect on the performance
• Resistance increases the potential energy
• Resistance increases the speed of the ride
• Resistance decreases the height of the ride

What type of energy is associated with the motion or position of an object?

• Mechanical energy
• Thermal energy
• Potential energy
• Kinetic energy
• Electrical energy

What determines the potential energy of a roller coaster at the top of a hill?

• The height of the hill
• The speed of the ride
• The curvature of the track
• The resistance on the ride
• The materials used for the track

How does the loss of mechanical energy due to friction affect a roller coaster ride?

• The loss of mechanical energy can result in a decrease in the ride's speed or height
• The loss of mechanical energy increases the ride's speed
• The loss of mechanical energy has no effect on the ride
• The loss of mechanical energy decreases the ride's potential energy
• The loss of mechanical energy increases the ride's potential energy
