Work, Energy, and Power: Crash Course Physics
When you hear the word, "Work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics and today, Shini is going to...

Interaction Forces
In this video Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant...

Newton's Third Law
In this video Paul Andersen explains how Newton's Third Law applies to all objects. When an object applies a force to another object (Action) and equal and opposite force (Reaction) is applied to the original object. Several scenarios...

Center of Mass
In this video Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external...

Why Do You Feel Strange In An Elevator Just After It Starts/Stops?
The sudden movement of the elevator disrupts the state of rest, causing the person to move upwards and resulting in a strange fuzzy sensation in the head. Some may experience drowsiness, lightheadedness, or even a mild headache. This...

Simple Truss Problem Q3 method of sections
For method of sections: 1) Draw a free body diagram of the entire structure. 2) Choose your section wisely (make sure the variables you want are part of section you've chosen). 3) Solve using static equilibrium equations (sum of forces =...

proof forces parallel to members in simple truss
Ever wondered why we neglect shear forces and bending moments in simple truss's? Here is a formal proof to show why we only consider axial forces (forces parallel to the members of the truss). It can only be done under three assumptions....

Reactions Example 1
Pin supports prevent movement in the x and y directions. This is why there are forces acting on the pin in the horizontal and vertical directions. Roller supports allow movement along one axis which is why there is only 1 force acting...
