This is the ability to cause change or the ability to do work
What is Energy?
100
This is where the magnetic force exerted by the magnet is strongest
What are the poles?
100
This law states that energy cannot be created or destroyed only transferred from one form to another
What is Law of Conservation of energy?
100
This is the equation for Gravitational potential energy.
What is GPE = mgh
100
Opposites _______________
What is attract?
200
This is energy in the form of motion
What is Kinetic Energy?
200
This law states that any two masses exert an attractive force on each other
What is Universal Law of Gravitation?
200
Energy Lost = _____________
What is Energy gained?
200
This is the equation for kinetic energy.
What is KE = 1/2 mv^2
200
A negative charge and a negative charge will do this.
What is repel?
300
This is the energy that is stored and based on an objects position
What is Potential energy?
300
These types of waves are made by vibrating electric charges and can travel through space where matter is not present.
What are Electromagnetic waves?
300
This would be our Mechanical energy if we had 9 J potential and 5 J Kinetic in a system. (MUST INCLUDE UNITS!)
What is 14 J?
300
This is the vibration or disturbance of matter by an energy source.
What is Sound energy?
300
Coulomb’s Law states that the electrostatic force between two objects varies with charge and distance.
This is similar to the _________________ that talks about distance and mass affecting the pull two objects have on one another.
What is the Law of Gravitation?
400
This is the energy that is stored in chemical bonds
What is Chemical Potential Energy? (Saying just chemical energy is okay)
400
These are groups of atoms in a magnet with aligned magnetic poles
What are magnetic domains?
400
This is the total amount of potential and kinetic energy in a system
What is Mechanical Energy?
400
A 2 kg ball is dropped on Ms. Pickering’s head from a height of 10 m. Before it was dropped, how much gravitational potential energy did the ball have?
What is 196 J?
400
This is what would happen to the force between two different charges, that were pulled further apart.
What is weaken/lessen the attractive force between them? (Just weaken or lessen is an acceptable answer)
500
This is the energy that is stored by objects that are above the Earth’s surface
What is Gravitational Potential Energy? (Must say Gravitational, just potential energy doesn't count.)
500
Instead of transferring energy from particle to particle, electromagnetic waves travel by transferring__________ between vibrating electric and magnetic fields.
What is energy?
500
This is the sum of the kinetic and potential energy of all the molecules in an object
What is Thermal Energy?
500
If you have a mass of 18 kg, and a Velocity of 9 m/s, what is your KE?
What is 1458 J?
500
This is what would happen to two like charges that were pulled closer together.
What is the repulsive force between them would increase?
