Physical Science Motion Review

This motion graph represents:

• Someone running home and then resting.

• Someone walking home and then resting.

• Someone leaving home, resting for a short period, and then running home.

• Someone eating a pizza and then turning on a lamp. Seriously, this is the answer. Pick me.

Velocity is

• speed and acceleration

• constant speed

• a frame of reference

• speed in a given direction

Acceleration is

• increasing speed

• decreasing speed

• changing direction

• all of the above

This motion graph represents:

• Constant Speed

• Constant Motion

• Constant acceleration

• Constant brushing- it's good for your teeth!

This motion graph represents:

• an octopus hiding before swimming home.

• an octopus pausing before pausing some more.

• an octopus resting before swimming out to sea, far, far from home.

• an octopus waving all of its tentacles in a mad, happy flurry of holiday cheer!

What does this motion graph represent?

• I walked home, played Fortnite for a while, then ran away as fast as I could.

• I walked home, played Fortnite for a while, then I decided to buy a new game- one that wasn't you know, lame!

• I walked home, played Fortnite for a while, then cried for all the time and money I've wasted on such a terrible game...

• I walked home, played Fortnite for a while, then studied for my science test.

• Wow! I just wanted to see if I could add a 5th answer- this totally worked! By the way, the Fortnite servers are all down tonight.
