Four Fundamental Forces
|
Gravity, Electromagnetic, Strong, and Weak
|
|
|
Strong Force
|
Holds protons and neutrons together. Also has complex equations
|
|
|
Normal Force
|
Can actualy be traced back to the Electromagnetic force, because, really the two objects' atoms are pushing against each other, not the objects themselves
|
|
|
Each force depends on an interaction, which means...
|
Each force needs two bodies or particles to exist, it cannot exist if only one particle or body is there
|
|
|
Gravity
|
attracts pancreases (and really any other objects)
|
|
|
Torque
|
lever arm X perpendicular force
|
|
|
Difference between torque and force
|
Torque is force of rotation: it has a direction while force does not. They also have two different equations
|
|
|
Center of Gravity
|
The average position of all the particles of weight in an object
|
|
|
Center of Mass
|
Where all the mass of an object is concentrated at
