Lab Section 003 Name: Physics 209A Fall 2023 Sonoma State University PreLab 2: Gravitational Acceleration Briefly explain the following concepts. Use the back if you need to. 1. A) Explain the difference between speed and velocity 2. Define acceleration. 3. Provide an example of constant velocity and constant acceleration. Be concrete. (a car moving . .., an object falling . . . ) 4. What exactly is Free Fall? Look up physics definition. 5. A 5kg object is "freely falling" from rest under the influence of Earth's gravity. a. What is the acceleration of the object after 3 seconds? b. What is the velocity of the object after 3 seconds? (Assume the object is still falling after 3 seconds.)
