Convert 3.2 mm to m.
What is 0.0032?
Find your displacement, from the time you wake up in the morning to the time you go to sleep at night.
What is zero.
A ball glides across a perfectly smooth surface (no friction at all, however unrealistic). According to Newton's 1st Law: if it moves at 2 m/s, will its speed be greater than this, less than this, or the same as this after 5 seconds pass?
What is the same?
Find the normal force on a penguin that weighs 22 N and stands still on a flat surface.
What is 22 N?
This quantity is represented by the slope of a position-time graph.
What is velocity?
Find your displacement if you walk 25 m north, 10 m south, then 5 m north.
What is 20 m, north?
What unit of measurement would you use to describe an object's inertia?
What are kg?
Find the weight of a 4.2 kg domestic housecat.
What is 41 N?
This quantity is represented by the slope of a velocity-time graph.
What is acceleration?
Find your average velocity if you walk 25 m north, then 10 m south, then 5 m north, in 45 seconds.
What is 0.44 m/s north?

If a 100 N person stands on two scales, with one foot on each scale, find the normal force shown on one of the scales.
What is 50 N?
If an object is slowing down, describe what its velocity-time graph will look like.
What is "it will become closer to zero as time passes?"
