What type of energy does a roller coaster at the top of a hill have?
A) Kinetic energy
B) Chemical energy
C) Potential energy
D) Radiant energy
Answer: C) Potential energy (It has energy stored because of its height.)
Why is thermal energy released during digestion, and what role does it play in the body?
Thermal energy is released as a byproduct when chemical energy from food is broken down and transformed during digestion. This release of heat helps to regulate and maintain the body’s internal temperature. Additionally, thermal energy supports the proper functioning of enzymes and metabolic processes, which operate more efficiently within a stable temperature range.
Which type of energy is stored in food?
A) Kinetic energy
B) Chemical energy
C) Electrical energy
D) Potential energy
Answer: B) Chemical energy (The energy stored in food is released when we digest it.)
Which of the following is NOT a type of potential energy?
A) Gravitational
B) Nuclear
C) Elastic
D) Sound
Answer: D) Sound (Sound energy is kinetic, as it involves moving particles.)
Which of these energy sources is renewable?
A) Coal
B) Oil
C) Wind
D) Natural gas
Answer: C) Wind (Wind is naturally replenished.)
Which of these best describes thermal energy?
A) Movement of objects
B) Heat energy
C) Stored energy in bonds
D) Sound from vibrations
Answer: B) Heat energy (Thermal energy is the energy of moving particles in a substance.)
What happens to energy when an object is lifted higher off the ground?
A) Kinetic energy decreases
B) Potential energy increases
C) Thermal energy decreases
D) Chemical energy increases
Answer: B) Potential energy increases (Height increases gravitational potential energy.)
