Energy which a body possesses by virtue of being in motion.
What is kinetic energy?
When you are at the peak of a roller coaster and you can see how far you could fall
What is an example of gravitational potential energy?
Where does the energy come from to make plants grow?
The sun.
Energy an object possesses because of its position in a gravitational field
What is gravitational potential energy?
When you touch a stove and burn your hand
What is an example of conduction?
A lava lamp does an excellent job demonstrating convection currents. What happens to the lava when it heats up?
Lava becomes less dense and rises
The energy an object has because of the movement of its molecules
What is thermal energy?
When the sun warms your face.
What is an example of radiation?
How does a glass of lemonade become cold when you put ice in it?
Heat energy from the lemonade is transferred to the ice cube.
A principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
What is conservation of energy?
When water boils, the cold water at the bottom heats up from the energy from the burner, and rises up. As the hot water rises, the cold water rushes in to replace it, which results in motion in the circular fashion.
What is an example of convection?
How is heat transferred from burning wood to your marshmallow when you are making a s'more?
Radiation
The process by which heat or electricity is directly transmitted through a substance
What is conduction?
When a pendulum swings upward, kinetic energy is converted to potential energy. When the pendulum stops briefly at the top of its swing, the kinetic energy is zero, and all the energy of the system is in potential energy. When the pendulum swings back down, the potential energy is converted back into kinetic energy. At all times, the sum of potential and kinetic energy is constant
What is an example of conservation of energy?
What kind of energy does the kinetic energy get transferred to when you apply the brakes on a car and why?
Heat/Thermal Energy due to Friction
