The relationship is stated by Newton's second law of motion, Force=Mass x Acceleration. -or-. F=ma. where F is the force, m is the mass, and a is the acceleration. The units are Newtons (N) for force, kilograms (kg) for mass, and meters per second squared (m/s2) for acceleration. The other forms of the equation can be used to solve for mass or ...
Physics Name: Worksheet ‐ Combining & Resolving Forces COMBINING FORCES Remember that force is a vector quantity. This means that when more than one force act concurrently on an object then the resultant (net) force can be found by adding the vectors head to tail.

How does a force P work?
Objective: To explain the concept of a Moment. If a Force P is applied at the midpoint of the free, rigid, uniform object, it will slide the object such that every point moves an equal distance. The object is said to translate. If the same force is applied at some other point as in second figure, then the object will both translate and rotate.
