|
|
Cross Product |
Generates a vector quantity |A||B|sin0 Multiply the 2 vectors and the angle inbetween them |
|
|
Right-hand rule |
Determines direction of the cross product Point thumb in the direction of the first vector and then fingers of the other and see the direction of your palm |
|
|
Gravity |
An attractive force |
|
|
Static friction (Fs) |
0<Fs<UsN |
|
|
Kinetic friction (Fk) |
Fk = UkN |
|
|
Weight |
Fg = mg |
|
|
First law |
All objects at rest will remain at rest unless acted upon by a unbalanced force |
|
|
Second law |
An object will accelerate when the vector sum of the forces acting on it result in some nonzero resultant force vector |
|
|
Third law |
To every action there is a reaction |
|
|
Terminal velocity |
an object in free fall will experience a growing drag force as the magnitude of its velocity increases, this drag force will eventually become equal in magnitude to the weight of the object prevent further acceleration |
|
|
Centripetal force |
Fc = (mv^2)/r |
|
|
Translational equilibrium |
Exists when the vector sum of all of the forces acting on an object is zero, this is the first condition of equilibrium |
|
|
Rotational equilibrium |
exists when the vector sum of all the torques acting on an object is zero, this is the second condition of equilibrium |
|
|
Torque |
T = r x F = rFsin0 |
