Objectives
· 1. Explain how to calculate force, mass, or acceleration using the formula F=ma after watching a video, and taking Cornell notes with a 3 or better.
1. Do Now: Calculating Forces Pre-Quiz
Independent
1. Watch THIS VIDEO and take the Newton's 2nd Law Cornell Notes:
Vocabulary
Newton's 1st Law
Constant Velocity
Vector Quantity
Newton's 2nd Law
Force (include units)
Mass (include units)
Acceleration (include units)
Proportional
Weight
Questions
1. Explain how Newton's 2nd Law relates to Newton's First Law.
2. Explain what the variables "F," "m," and "a" represent in the formula F=ma
3. Draw and explain the brick example starting at 1:25
4. Explain the difference between mass and weight.
5. What unit is a Newton equal to?
6. Why is it important that the newton is equal to kg*m/s^2?
7. If you exert a 10N force on an object that has a mass of 2kg, what is the acceleration? (use the formula F=ma to calculate this)
8. If we double the mass of the object in problem #7 to 4kg, and use 20N of force to push it, what is the new acceleration?
9. (not from the video) Calculate the force needed to accelerate a 100 kg mass at 5 m/s^2
Summary: Today I learned.....
Cornell Notes Criteria for success:

- 8 or more of the questions are answered fully AND correctly, using information and examples from the video
- A summary of what was learned is at the bottom, using 2-3 complete sentences.
4= All success criteria is met
3= 3/4 success criteria is met
2= 2/4 success criteria is met
NP = none of the success criteria is met
Optional (ONLY AFTER YOU ARE FINISHED!!!!)
1. Play with this PhEt simulation to explore how changing masses affect the amount of force needed to move an object
2. Play the NET FORCE GAME and try to beat a score of 6 (the highest anyone has scored has been 19)
3. Watch THIS VIDEO on roller coaster Physics
4. Play the roller coaster building game
