Question | Answer |
accelerate | rate at which the velocity changes |
acceleration includes | rate of slowing down, speeding up, going backwards and turning |
Acceleration formula | final velocity-starting velocity time it takes to change velocity |
Acceleration is expressed as | (m/s/s) |
increase in speed | positive acceleration |
decrease in speed | deceleration |
Motion is calculated by using a | reference point |
speed is | the distance traveled and how long it took you to get there |
speed average formula | total distance total time |
velocity | the rate of an object going in a certain direction |
velocity always includes | change in direction |
circular acceleration is called | centripetal acceleration |
scientists use newton's to measure | force |
force doesn't always cause something to | move |
Force means | to push or pull |
net force | the result of combining all the forces put on an object |
net force formula | larger net force- smaller net force =the final direction |
Unbalanced forces cause | |
objects can move when | unbalanced forces are removed |
friction | a force that opposes motion of two touching surfaces |
friction is increased by | rougher surfaces |
turning an object into a different position does not effect the | amount of friction |
Sliding friction | friction caused by two surfaces sliding past each other |
Rolling friction | wheels on another surface |
fluid friction | opposes movement through fluids |
static friction | opposes motion |
lubricants | used to reduce friction |
gravity | attraction of two or more objects |
law of gravity | crated by newton |
gravity force increases | mass increases |
gravity decreases | distance |
weight | measurement of gravity |
mass | measurement of matter |
