Question | Answer |
---|---|
friction | the opposite of what motion is moving |
static friction | when force is going somewhere else |
sliding friction | when an object slides on top of another object |
rolling friction | when a object rolls on another object |
fluid friction | a liquid like water or air |
gravity | what holds things on the ground |
mass | the objects weight |
weight | the objects mass |
free fall | falling without being pushed |
air resistance | when an object falls slow due to air when gravity pushes it |
projectile | an object thrown with force |
compression | heat |
tension | when something has thermal energy |
force | when an object is pushed or pulled |
newton | magnitude or strength |
unbalanced forces | can cause the velocity to change |
net force | determines when on object is moving or seed or direction its moving |
balanced forces | when both sides of the object has the same force |
inertia | when an object resists a change to motion |
momentum | moving an object |
conservation of momentum | when momentum is transferred |
momentum | moving an object |
