Force and Motion
Term | Definition |
---|---|
acceleration | if speed and or direction change |
velocity | speed in a particular direction |
unbalanced force | causes a change in motion of something |
balanced force | position or motion will not change- equals zero |
kinetic energy | energy in motion |
potential energy | energy based on objects position |
speed | how fast something moves |
force | push or pull |
law of conservation of energy | energy cannot be created or destroyed, only transfrormed |
friction | the force of resistance of two surfaces touching eachother |
work | use if force to move an object |
inertia | the tendency of an object at rest to stay at rest and an object in motion to stay in motion |
Newton's 1st Law | Inertia |
Newton's 2nd law | F=MA Force equals mass times acceleration |
Newton's 3rd Law | For every action there is an equal and opposite reaction |
mass | how much matter is in an object |
weight | measure of the gravitational pull on an object |
