This is the slope of a position-vs-time graph.
What is velocity?
100
The resistance to a change in motion, directly proportional to an object's mass?
What is inertia?
100
This is the value of the acceleration due to gravity on the surface of the Earth, rounded to one decimal place.

When friction does work on an object, this is what happens to energy
What is converts into thermal energy?
100
This is the unit for mass.
What is kg?
200
A runner completes three laps around a 400-meter track, ending where they started. This is their total displacement.
What is zero?
200
This type of force always acts perpendicular to the surface an object is resting upon.
What is the normal force?
