Exploring Kinetic and Potential Energy in Roller Coasters

What does the law of conservation of energy state about energy in a closed system?

• Energy remains constant and only changes form

• Energy can only be transformed into work

• Energy can be created and destroyed

• Energy gradually decreases over time

What is the definition of work in a physical context?

• Work is any kind of physical or mental activity

• Work is the potential energy stored in an object

• Work is moving an object using force over a distance

• Work is the transfer of energy through motion

What happens to the roller coaster's energy as it gains speed?

• It loses all its potential energy

• It converts potential energy into kinetic energy

• It gains more potential energy

• It remains constant without any change

During the ride, when the roller coaster is moving upwards, what change occurs in its energy?

• Kinetic energy is converted into potential energy

• Potential energy is lost completely

• Kinetic energy remains constant

• No energy conversion happens

What is the primary process occurring throughout a roller coaster ride in terms of energy?

• Conversion between electrical and mechanical energy

• Interchange between potential and kinetic energy

• Generation of new energy forms

• Continuous loss of mechanical energy
