| word | Definition |
|---|---|
| acceleration | change in velocity divided by the amount of time needed for the change to take place |
| balanced force | describes forces that are equal but opposite in direction |
| chemical energy | by the law of the convertion of energy, it must under go a change equal and oppsite to the change of heat energy in a reaction |
| displacement | measures the distance and direction from a strating point to a ending point |
| distance | the extent of space between two objects or places |
| electriacl energy | energy made avaliable by the flow through conductors |
| electromagnetic waves | transverse wave that can travel through matter or space and are produced by motion of electrically charged particals |
| force | a push or pull |
| friction | any force that resiets motion |
| gravity | the natural force of attraction exerted by a celestial body or natural force of attraction between any two massive bodies |
| kinetic energy | the energy an object has becuase of its motion |
| mechanical wave | a type of wave that can only travel through matter |
| newton's 1st law | evry object moves in a straight line unless acted upon by a force |
| newton's 2nd law | the acceleration ogf an object is directly proportional to the net force exerted and inversely porportional to the object's mass |
| newton's 3rd law | for every action there is a equal and oppsite reaction |
| potentional energy | the energy of a particale or system of particals derived from position, or condtion, rather than motion |
| speed | distance traveled divided by the time needed to travel that distance |
| thermal energy | energy which is charateristic for thermal neutrons at room temperature |
| unbalanced force | describes unequal forces acting on an object |
| velocity | speed and direction of a moving body |
