Physics
1 Dimensional Motion
Chapter 2 Section 3 – pages 60-65

2. Falling Objects Freely falling objects undergo constant acceleration
Free fall – motion of an object falling with a constant acceleration
Free fall  g (acceleration due to gravity)
 has magnitude and direction

3. Falling Objects
a = -g = m/s2 = acceleration down due to gravity
What goes up, must come down
If any object is thrown up into the air, the acceleration is always -9.81m/s2
Always have same acceleration down
Magnitude and direction of velocity are
changing

4. Falling Objects
Displacement in the vertical direction (up and down) = Δy
Replace “a” with “g”
