Guide.
Force - answer✔Defined by magnitude, direction, and point of application
Moment - answer✔Defined by a force, perp. distance between the force's line of action, and
point of interest
Rigid Body - answer✔A body in which internal points do not change
Deformable Body - answer✔Internal points change relative distances when a force is applied
1st Newton Law - answer✔Equilibrium: A particle's velocity will remain constant unless there is
a nonzero force acting on it
2nd Newton Law - answer✔F = ma; If subjected to an unbalanced force, a particle accelerates in
the same direction as that force
3rd Newton Law - answer✔Forces of action and reaction between two bodies are equal in
magnitude, opposite in direction, and collinear
Vector - answer✔Magnitude and direction
Scalar - answer✔just magnitude
