Kinetic Energy
What is kinetic energy?
The energy an object has due to its motion.
What is potential energy?
The energy stored in an object due to its position or state.
Is a stretched spring an example of kinetic or potential energy?
Potential
What is thermal energy?
Heat or Heat energy
Energy
The ability to do work or cause change.
Give an example of kinetic energy
A moving car or a rolling ball.
Provide an example of potential energy.
Tawes says:
Is a running dog an example of kinetic or potential energy?
Kinetic
What happens to particles in a substance when it is heated?
Answer: They move faster and spread apart.
Kinetic Energy
The energy of an object due to its motion.
What factors affect kinetic energy?
The mass of the object and its velocity.
What two types of potential energy are commonly recognized?
Gravitational potential energy and elastic potential energy.
Identify the type of energy: water flowing in a river.
Kinetic
What is conduction?
Answer: The transfer of thermal energy through direct contact between materials
Potential Energy
The energy stored in an object due to its position or condition.
How does kinetic energy change if the speed of an object doubles?
The kinetic energy decreases.
Classify the energy: a charged battery.
Potential
Identify the type of energy: a roller coaster at the top of a hill.
Potential
Describe convection.
Answer: The transfer of thermal energy by the movement of fluids (liquids and gases).
Law of Energy Conservation
Energy cannot be created or destroyed; it can only change forms.
How does kinetic energy change if the speed of an object doubles?
The kinetic energy increases by four times.
What is the relationship between kinetic and potential energy in a pendulum?
Answer: It continuously converts potential energy to kinetic energy and back as it swings.
How does thermal energy relate to temperature?
Answer: Higher thermal energy means higher temperature and faster particle movement.
