Day 14 in SCI110: Newton's Laws
- Spring 2005 Schedule
- Last time: compound motion
- Some leftovers from last time:
- net force
- inertia
- free fall - Galileo and Aristotle, d=1/2*g*t2
- Discussed free fall experiment
- plotted distance versus time - parabolas
- plotted the square root of distance versus time - another calculation of g, the acceleration due to gravity
- units of acceleration: m/s/s
- Conducted projectile motion experiment
- Reminder: Quiz next time (physics)
- Today:
- Compound motion
- velocity and acceleration as vectors
(arrows with length and direction -- see p. 33)
- Practice: linear motion
- Sample motions
- Revisit Questions: p. 45 #1; Group B: 2-3
- Horizontal and vertical
- Circular
- Newton's Laws of Motion (Chp. 2: 32-38)
- Questions: p. 45/8-12; Group B 10
- Projectile Motion lab, part II (p. 60)
- Discuss group presentations (time permitting)
- Homework:
- Prepare for physics quiz
- Prepare for group projects
