the ability to do work or cause change
ENERGY
if an objects position changes relative to another object is it...
in motion
Define maximum.
the most, the greatest
Power is measure in
Watts
Energy is measured in..
Joules and/or Calories, calories
the rate at which work is done, and equals the amount of work done on an object in a certain amount of time is known as..
POWER
How are energy and motion related?
It takes energy for motion to occur!
What is kinetic energy?
the energy an object possesses by virtue (because of) movement
Kinetic energy of an object depends on the objects..
speed or mass
energy that results from the position or shape of the object
What are the two types of potential energy?
Gravitational and Elastic PE
Explain why a running deer has kinetic energy.
It is moving!!
Energy an object has due to its motion, shape, position, or a combination of those factors.
What is nuclear energy?
Energy store in the nucleus of an atom!
Thermal energy is..
total potential/kinetic energy of particles in an object. Relates to temperature.
What type of energy is in the food you eat, in the cells of our bodies & in glow sticks?
Chemical Energy
What are some of the relationships among thermal energy, kinetic energy, particle movement, and temperature?
When a substance is high temp its particles are moving quickly which means they have more kinetic energy. If the KE of particles increases, the thermal energy of the substance also increases!
Thermal Energy from the hotness of the soup as well as chemical energy stored in the soups ingredients.
What is the difference between energy transfer and transformation?
Energy transfer is the same type of energy transferring from one object to another while Energy transformation is the change of one type of energy to a different type of energy.
What does it mean to say that energy is conserved in a transformation?
Total energy before transformation is the same after transformation just in a different form.
After a tornado moves through a forest, what kinds of evidence would there be of energy transfers or transformation?
Broken branches/snapped tree trunks would be evidence that kinetic energy of the wind had transferred to the trees. Branches on the group indicate PE transformed into kinetic energy as they fell.
What is the law of conservation of energy?
No energy can be created or destroyed only transformed or transferred.
What affects gravitational pe and how?
Height because the higher the object the more GPE it contains.
Why is chemical energy considered a form of potential energy?
Because chemical energy has potential to provide energy to become mechanical energy.
Name 7 types of energy.
