Intro to Energy
What is kinetic energy?
Kinetic energy is the energy of an object that's due to motion.
What is temperature?
Temperature is related to the average kinetic energy of the object's particles.
What is the atmosphere?
The atmosphere is the mixture of gases that surround Earth.
What is wind?
Wind is the movement of air from higher pressure going to areas with lower pressure.
What's potential energy?
Potential energy is energy stored up due to position, condition, or chemical composition.
What is thermal energy?
Thermal energy is the total kinetic energy of all particles in a substance.
What is air pressure?
Air pressure is the measure of force with which air molecules push on an area of a surface.
What are convection cells?
Convection cells is the patter air moves in (circular patterns).
Which one would have more kinetic energy; A bowling ball or a soccer ball both moving at the same speed?
The bowling ball would have more kinetic energy, because it has more mass.
What happens when you add heat to an item?
When you add heat to an item, it can change the state of matter.
What happens to the air pressure when the altitude increases?
When the altitude increases, the air pressure decreases.
What is the Coriolis Effect?
The Coriolis Effect is the apparent curving of the path of a moving object from an otherwise straight path due to Earth's rotation.
What type of energy is a hamburger?
List the three ways of transferring heat.
Three ways of transferring heat includes conduction, convection, and radiation.
What happens to the density when a substance expands due to heat?
When a substance expands due to heat, the density will decrease.
What are jet streams?
Jet streams are narrow belts of high-speed winds that blow from east to west, between 7-16 km above Earth's surface.
What does the Law of Conservation state?
The Law of Conservation states that energy can be neither created or destroyed, but can only change forms.
Calories are equal to the amount of energy needed to raise the temperature of 1 g. of water by 1 degree Celsius. It can be measure in joules.
What is convection?
Convection is the transfer of energy due to the movement of matter.
How does a land breeze work?
The land breeze happens during the night. The land cools faster than water, and so air rushes towards the sea.
