Term | Definition |
---|---|
gravity | the force between 2 objects |
friction | the force between 2 resisting surfaces |
static friction | the force acting on an object not moving |
sliding friction | the force acting on an object sliding |
rolling friction | the force acting on an object rolling over a surface |
fluid friction | the force of an object going through a liquid or gas |
weight | a downward force due to mass because of gravity |
normal force | the upward force that helps support the weight |
force | the push or pull acting on an object |
"N" stands for | Newton |
free-body diagram | Drawing of force |
net force | all the forces put together |
terminal velocity | the resistance of a falling object |
Newton's first law | an object at rest stays at rest |
Newton's second law | force=mass*acceleration |
Newton's third law | every action has and equal and opposite reaction |
mass | kg |
momentum | kgm/s |
velocity | m/s |
force | N |
