1. The standard acceleration due to gravity (or standard acceleration of free fall), is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as:
2. A projectile is fired vertically upward at an initial velocity of +32 m/s. How high will it rise and how long will it take the projectile to reach that height?
3. The overall change in position is know as .....
4. What is displacement?
5. Connor, a long-distance runner, begins at the starting line and completes 4 laps on a 400 m track. What is the total distance and displacement of Brendon when they cross the finish line after the 4th lap?
6. What is the SI unit of distance?
7. Acceleration only takes place when things speed up.
8. A solid cylinder rotates with constant angular acceleration about a fixed axis. The cylinder's moment of inertia (I) about the axis is 5.0 kg-m$^{2}$ . At time t = 0 s, the cylinder is at rest. At time, t = 2.0 s, its angular velocity is 1.0 rad/s. Q; What is the rotational kinetic energy of the cylinder at t = 2 s?
9. In each of the following cases, determine where the car has no acceleration?

16. Which is NOT a step in the scientific method?
17. A man runs 650 m east and then turns and runs 850 m west. This takes him 240 seconds. What is the man's average SPEED for the run?
18. How long would it take a car, starting from rest and accelerating uniformly in a straight line at 5 m/s$^{2}$, to cover a distance of 200 m?
19. What does this symbol mean:$\Delta$
20. An airplane accelerates down a runway from rest at 3.20 m/s$^{2}$ for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.Which equation is appropriate?
