If you increase force, but keep acceleration the same, what happens to mass?
It increases. (What you do to one side of an "=" you do to the other.)
200
The definition of acceleration.
What is "How velocity changes over time"?

Turn this equation into a form that solves for m.
F=m*a
What is "m=F/a"?

A baker carefully measures the weight of some milk for a recipe. She reads the number off her scale... 5.49 g. Returning to her recipe book, she groans. She needed the scale set to milligrams! Help a woman out, will ya?
(How many milligrams of milk does she have?)
What is 549 mg?

A dog pulls at a stick he found wedged under the fence at his yard. Suddenly, a bigger dog on the other side of the fence comes up and starts pulling the stick too! If they are both pulling with the same acceleration, which dog will get the stick? (Answer must include why, as shown on a +/-/# chart)
What is the big dog because it has more mass.
Chart: F=m*a -> +=+*#

The relationship between acceleration and velocity.
What is "Acceleration tells us how much the velocity is changing in an amount of time."

3 students are arguing about whose backpack is heaviest.
Jay says, "My backpack is like 10 Hg."
Mari says, "Well mine's like 1000 g! It's way heavier!"
Bobert chimes in, "That's nothing! My backpack is 1,000,000 mg!!"
Who has the heaviest backpack?
Nobody! They are all exactly the same mass- 1 kg, 10 hg, 100 dg, 1000 g...

You and your friend are having a cart race in the grocery store. (The store workers are quite angry at you both, this is the 5th time this month!)
You race to the end of the aisle, only to have your friend pull way ahead of you super fast! You know you were pushing your cart with just as much force! What happened?
Your friend didn't have stuff in their cart, but you did.
In terms of our chart (Compare you to friend): #= - * +

A car gets on an on-ramp for the freeway. The street before the on ramp has a speed limit of 25 mph. The freeway speed limit is 60 mph. If it takes it 5 seconds to do it, will the acceleration be positive or negative? Why?
What is positive because the final velocity is bigger than the initial velocity?

Turn this equation into a form that solves for t.
a=(v_f -v_i)/t
What is
t=(v_f -v_i)/a
