Question | Answer |
---|---|
constant | not changing |
parallel circuit | there is more than one path for current to flow |
series circuit | a certain path for current to flow |
electric current or current | the flow of electrically charged particles, including electrons |
resistance | a part of a circuit that slows or stops the current |
voltage | the potential difference between ends of a circuit |
potential difference | A difference in electric potential that is needed for current to flow |
potential energy | stored energy PE=m x g x h |
Conservation of Energy | Energy cannot be created or destroyed, but it can be transformed from one form to another |
kinetic energy | Energy of motion |
electrical potential energy | potential energy particles have because of how close they are together |
oscillation | Moving back and forth at a regular interval |
gravity | an attractive force between two objects |
g | acceleration due to gravity |
thermal equilibrium | when two objects reach the same temperature |
heat | energy moving from a warmer object to a cooler object |
momentum | an object's resistance to slowing, stopping or speeding up |
Law of Conservation of Momentum | an object's momentum cannot change unless a force outside of it pushes or pulls it |
impulse | a force applied over time |
mass | how much stuff something is made of |
force | a push or a pull |
acceleration | how fast something changes speed or velocity |
velocity | how fast something moves and in what direction |
Newton's 2nd Law | More mass, less acceleration and more force, more acceleration F=m*a |
friction | a force which pushes against motion |
air resistance | The friction caused by moving against air particles. It is especially important when something is flying through the air |
Newton's 3rd Law | For every force, there is an equal and opposite force |
period | how much time it takes for a wave to pass or a pendulum to swing back and forth |
amplitude | how high a pendumlum swings or the height or the depth of a wave |
frequency | number of waves per second |
wavelength | distance from the top of one wave to the top of the next |
longitudinal wave | a wave whose particles move the same direction as the wave |
photovoltaic | a device which turns light eneryg into electrical energy |
MRI | a device in the hospital which uses strong magnets and radio waves to form images of the body |
refraction | when a wave bends |
Equipotential Line | An invisible line across which there is a potential difference |
