Force and free body diagrams Flashcards
Define force and free body diagrams with respect to their function
Force and free body diagrams are drawings that are used to show and visualize the forces that act on an object and affects its motion
The main difference between force and free body diagrams
Force diagrams show the object that is being acted upon. However, free body diagrams represent the object with a simple dot.
In what scenario does force diagram have an advantage over free body diagram
When the object rotates or in situations involving torque and you want to know on which exact point, the forces are acting.
State newton’s first law of motion
An object at rest, remains at rest or in motion, stays in motion until acted upon by a net external force.
In what scenarios and professions are free body diagrams with relation to Newton’s first law used.
It is used by architects, civil engineers, etc in building static stuctures, like houses, bridges, etc
State newton’s second law of motion
The aceleration of a system is directly proportional and in the same direction as the net external force acting on the system and inversely proportional to its mass
In what scenarios and professions are free body diagrams with relation to Newton’s second law used.
It is used by professions which need to understand acceleration such as coaches to coach athletes, aeronautical engineers to make planes, etc.
State newton’s third law of motion
When one body exerts force on a second body, the first body experiences a force that is equal in magnitude but opposite in direction to the force which it exerts. ( Every action has an equal but opposite reaction)
