S8P2., S8P1b., and S8P3b. Spiral Review

What is the difference between temperature and thermal energy?

• Temperature measures the total energy of all particles in a substance.

• Temperature measures the average kinetic energy of particles, while thermal energy is the total energy of all particles in a substance.

• Thermal energy is the measure of how hot or cold an object is.

• Temperature and thermal energy are the same thing.

What is the formula for calculating kinetic energy?

• Kinetic Energy = mass * speed

• Kinetic Energy = 1/2 * mass * speed^2

• Kinetic Energy = mass * speed^2 / 2

• Kinetic Energy = 2 * mass * speed

What describes the particles in a solid?

• They vibrate in place within a fixed volume.

• They move freely and fill the entire container.

• They are arranged randomly and can change shape easily.

• They are in a gaseous state and have no fixed volume.

What is mass?

• Mass is how much matter is in an object.

• Mass is the weight of an object in a vacuum.

• Mass is the volume of an object.

• Mass is the density of an object multiplied by its volume.

What is potential energy?

• The energy of an object in motion.

• The energy stored in an object due to its position or state.

• The energy released during a chemical reaction.

• The energy associated with the temperature of an object.

What happens to the kinetic energy of an object if its speed doubles?

• The kinetic energy remains the same.

• The kinetic energy increases by a factor of two.

• The kinetic energy increases by a factor of four.

• The kinetic energy decreases by a factor of four.

How does increasing temperature affect the movement of particles in a substance?

• Increasing temperature causes particles to move slower.

• Increasing temperature causes particles to move faster.

• Increasing temperature has no effect on particle movement.

• Increasing temperature causes particles to stop moving.

What is the relationship between mass and weight?

• Weight is the force exerted by gravity on an object's mass.

• Mass is the force exerted by gravity on an object's weight.

• Weight and mass are the same and can be used interchangeably.

• Weight is independent of mass and varies with location.

What is weight?

• Weight is the gravitational pull on an object.

• Weight is the mass of an object.

• Weight is the volume of an object.

• Weight is the density of an object.

What is the effect of gravity on potential energy?

• Potential energy decreases with height in a gravitational field.

• Potential energy remains constant regardless of height.

• Potential energy increases with height in a gravitational field.

• Potential energy is unaffected by gravity.
