| 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 |
