Science Quiz #5

Which statement does NOT correctly compare silicon with another element?

• Silicon is a better conductor of electricity than sulfur.

• Silicon conducts electricity as well as copper does.

• Silicon is a solid at room temperature, but argon is a gas.

• Silicon is less malleable than silver.

Which of these correctly describes the potential energy and the kinetic energy of the bicycle rider?

• When the rider is at the top of the hill, her potential energy is the greatest, and her kinetic energy is the least.

• As the rider moves up the hill, her kinetic energy increases, and her potential energy decreases.

• When the rider goes down the hill, her potential energy increases, and her kinetic energy decreases.

• As the rider reaches the bottom of the hill, her kinetic energy and her potential energy decrease.

What is the difference between potential energy and kinetic energy?

• Potential energy is the energy of an object due to its position, while kinetic energy is energy due to its motion.

• Potential energy is the energy of an object due to its motion, while kinetic energy is energy due to its position.

• Potential energy is the energy of an object due to an applied force, while kinetic energy is energy stored after the applied force.

• Potential energy is the energy stored after an applied force, while kinetic energy is the energy used from the applied force.
