types of speed

constant speed: when the speed stays the same

an example is a car on cruise control

hair dryer because it blows the same amount of air when it comes out

variable speed: when the speed changes

an example is a car because a car changes how fast it goes

an analogy is wind because wind changes speed

average speed: over all speed of many different speeds

to find swimmers average you have to calculate all of their speeds

running because you running changes at different speeds so you would need to take all of you totals


the speed at any given moment and time

ex: a car moving and measuring you speed on snapchat

analogy: how fast you were at a certain time
