1. Newton’s Laws and Kinematics Mr. Hsieh

2. Just the basics Position: Measured in meters Time: Measured in seconds Velocity: Measured in m/s Positive and negative signs matter! Acceleration: Measured in m/s2 Positive and negative signs matter!

3. General Kinematic Equation Final velocity = v0 + a(t) Distance traveled = v0 t + (½)at2 (Final velocity)2 = (v0 t)2 + 2ad Distance traveled = [(v0 + vf)/2]*t

4. Gravity Constant acceleration = -9.8 m/s2 The velocity of an object dropped from rest: 0 m + (Grav constant)*(time in seconds) … Of object dropped from height (15 meters): 15 m + (Grav constant)*(times in seconds)

5. Important! Learn these equations backwards and forwards! For gravity all you have to remember is 10m/s2 Review questions: How do you solve for acceleration if you have initial velocity, final velocity, and time? How do you solve for distance if you have final velocity, initial velocity, and acceleration?
