Velocity Problems (page 3)1. You can run 500 meters East in 100 seconds. What is your velocity?

2. Jose can crawl 40 meters West in 4 minutes. What is his velocity?

3. It takes a soccer ball 10 seconds to move 100 feet West. What is its velocity?

V = 500 m / 100 s = 5 m/s east2. Jose can crawl 40 meters West in 4 minutes. What is his velocity?

3. It takes a soccer ball 10 seconds to move 100 feet West. What is its velocity?

V = 40 m / 4 minutes = 10 m / min west3. It takes a soccer ball 10 seconds to move 100 feet West. What is its velocity?

V = 100 feet / 10 seconds = 10 ft. / s west

Velocity Problems (page 3)4. LeBron James can run 90 feet (towards the basket) in 30 seconds. What is his velocity?

5. A man can travel 555 miles in 11 hours. What is his velocity?

6. A Porsche can travel 100 feet North in 6 seconds. What is its velocity?

Velocity Problems (page 3)4. LeBron James can run 90 feet (towards the basket) in 30 seconds. What is his velocity?V = 90 feet / 30 s = 3 ft/s towards the basket5. A man can travel 555 miles in 11 hours. What is his velocity?

6. A Porsche can travel 100 feet North in 6 seconds. What is its velocity?

Velocity Problems (page 3)4. LeBron James can run 90 feet (towards the basket) in 30 seconds. What is his velocity?V = 90 feet / 30 s = 3 ft/s towards the basket5. A man can travel 555 miles in 11 hours. What is his velocity?V = 555 mi / 11 hrs. = 50 mi / hr6. A Porsche can travel 100 feet North in 6 seconds. What is its velocity?

A man can travel 555 miles in 11 hours. What is his velocity?V = 555 mi / 11 hrs. = 50 mi / hr6. A Porsche can travel 100 feet North in 6 seconds. What is its velocity?V = 100 ft / 6 s = 16.7 ft/s

Velocity Problems (page 3-4)7. I threw the ball (to the South) at a speed of 8 meters / second. It travelled 4 meters. How much time did it take?

Velocity Problems (page 3-4)7. I threw the ball (to the South) at a speed of 8 meters / second. It travelled 4 meters. How much time did it take?V = Δd/ΔtΔt = Δd/VΔt = 4m / (8m/s) = 0.5 s

Velocity Problems (page 3-4)8. I rolled a bowling ball at a speed of 3 feet / second. It travelled for 4 seconds. How far did it travel?

Velocity Problems (page 3-4)8. I rolled a bowling ball at a speed of 3 feet / second. It travelled for 4 seconds. How far did it travel?V = Δd/ΔtΔd = VΔtΔd = VΔt = (3 ft / s)(4s) = 12 s

Paper Air Plane Lab (page 5)

PROCEDURE: Part I. Observation:

1. Construct an airplane out of paper. This will be the fist test plane or the Control.

2. Once in the hall, behind the line, throw your airplane.

Someone will be keeping time from the time you let go until it touches the ground.

The Distance will also be measured from where your plane landed.

3. Record your measurements in the data table.

4. Record your observations of how your plane performed in flight.

Calculate the velocity

Flight # Distance Traveled Time of Flight Average Velocity Observations

Part II: Form a Hypothesis:

1. Make a hypothesis of what you could change on your plane to make it travel further and faster. (add weight, change a fold, add tape)

________________________________________________________________________

_______________________________________________________________________.

Part III: The Experiment

2. Make one change to your plane to test your hypothesis.

3. Repeat 2-5.

Part IV: Make Observations and Revise Your Hypothesis.

1. Was your hypothesis correct? ___________ Did your velocity improve?______

2. Record your observations of how your plane performed in flight.

3. Revise your hypothesis. Make a hypothesis of what you could change on your plane to make it travel further and faster. (add weight, change a fold, add tape)
