The Big Five |
1. d = 1/2 ( Vinitial - V)t missing a 2. v = Vinitial + at missing d 3. d = Vinitial t + 1/2 at^2 missing v 4. d = Vt - 1/2at^2 missing initial v 5. v^2 = initial V^2 + 2ad missing t |

|
Velocity Vs. Time Graph |
slope = acceleration are underneath = displacement |
|
|
Position vs Time Graph |
slope = velocity |
|
|
Newton's First Law of Motion
|
an object will stay in motion . ....... inertia - natural resistance to change of velocity |
|
|
Newton's Second Law of Motion |
F net = mass * acceleration |
|
|
Newton's Third Law of Motion |
Every action has an opposite and equal reaction... F1-on-2 = -F2-on-2 |
|
|
Weight |
w = mg |
|
|
Gravitational Force between Objects |
F grav = G (Mm/r^2) |
|
|
Static Friction |
when object isn't moving |
|
|
Sliding Friction |
when object is moving |
|
|
Force of Friction |
Force of friction = Coefficient of Friction * Normal Friction |
