Term | Definition |
---|---|
speed | rate of how fast or slow something is moving |
velocity | speed and direction of an object |
acceleration | change in velocity |
force | push or pull one object exerts on another |
gravity | force or attraction on or near the Earth |
balanced forces | forces equal in strength pulling against each other |
net forces | force resulting in unbalanced forces acting on each other |
inertia | property of matter that resists change in velocity |
kinetic energy | energy of motion |
potential energy | energy due to an objects condition or position |
1st law | object at rest stays at rest, an object in motion stays in motion |
momentum | mass multiplied by velocity |
2nd law | F=MA |
3rd | For every action there is an equal and opposite reaction |
motion | action of moving or changing position |
mass | measure of a body's resistance to change in velocity |
weight | force that gravity puts on an object |
joules | unit used to measure energy |
