Where do we measure distance between a planet and moon from when considering gravitational force?
The outside edge of each
The inside edge of each
The center of mass of each
It doesn't matter
If distance quadruples between two planets, how does the gravitational force between them change?
By a factor of 4
By a factor of 1/4
By a factor of 16
By a factor of 1/16
What is happening to the velocity in Section C, and what does that indicate about acceleration
V is increasing, so a is positive
V is constant, so a is positive
V is increasing, so a is 0
V is constant, so a is 0
Which velocity vs time graph correctly describes a person walking forward with constant speed?
How do you calculate average velocity from a distance vs time graph?
Run/Rise
Rise/Run
Multiply distance and time

A chicken crosses the road, which is 10 m wide. It takes 20 seconds to cross. How fast was the chicken?
2 m/s
0.5 m/s
10 m/s
20 m/s
A car backs out of a driveway at 5 m/s, then drives forward at 5 m/s. Which is the correct assignment of those values?
vi = -5 m/s vf = 5 m/s
vi = 5 m/s vf = -5 m/s
vi = -5 m/s vf = -5 m/s
vi = 5 m/s vf = 5 m/s
