Q1. The spreadsheet starts with the object at rest. What is the initial velocity (v.) of

an object at rest?

Q2. Answer all parts of this question:

1. What is the velocity of the object at

1. 0 seconds

2. 1s

3. 2s

4. 3s

5. 4s

6. 5s

2. What is the difference between each of these velocities?

3. What is the significance of this difference (what does it tell us)?

Q3. Set the slider for a number of different values (especially small ones like 1 m to 3

m) and look at the Height vs. Time graph before answering the parts of this question.

1. Describe the shape of the Height vs. Time graph.

2. What does the shape of the Height vs. Time graph tell you about the

motion of falling objects?

Q4. Set the slider for a number of different values and look at the Velocity vs. Time

graph before answering the parts of this question.

1. Describe the shape of the Velocity vs. Time graph.

2. What does the shape of the Velocity vs. Time graph tell you about the

velocity of falling objects?

3. What does this graph look like after the object reaches the ground?

What is the velocity of objects after they reach the ground?

Q5. Velocity is a vector so it has a direction. What is the direction of our object's

velocity?
