Contact Forces
In this video Paul Andersen explains how contact forces result from interatomic forces. The following forces are explained at the interatomic level: normal force, applied force, friction force, tension force, spring force, and buoyant...

Force vs. Time on a Dynamics Cart
When the forces in a free body diagram don’t change students often think that Newton’s Second Law will yield the same results. This demonstration shows that is not true. This is a step-by-step analysis of tension force as a function of...

Tension and Pulleys example 2
To solve problems like these, make isolated cut selection to find each of the variables one at a time. Then use that fact that under reasonable assumptions (massless rope and frictionless pulleys) then the tension in the cable must be...

Torque - Mass on Plank with String
A 0.300 kg mass rests on a 0.395 m long, 0.764 kg, uniform wooden plank supported by a string as shown in the figure. If the mass is 0.274 m from the wall and the angle between the string and the plank is 32.1°, (a) What is the force of...

Pulleys and Tension in static equilibrium Summary
If a pulley is in static equilibrium and the following is true: 1) Rope is massless 2) Pin is frictionless Then the tension in the cable will be constant everywhere along the cable. There is only 1 force (tension) that is internal in the...
