Disk rolling down incline problem
Find the acceleration of the center of mass of the disk. 1. Use F = ma AND M = I alpha 2. Assume pure roll ie a = r alpha 3. Check validity of assumption ie, F less than Fmax 4. If F less than Fmax, THEN assumption is true 5. If F...

Tension and Pulleys in static equilibrium Example 1
Here we solve for the constant tension in the rope of a pulley system in static equilibrium. Remember the assumption that the tension is uniform everywhere is valid if: 1) The system is in static equilibrium 2) The rope is massless 3)...

Kinetic Friction and Static Friction intuition
Hey guys, this video covers the intuition behind friction. Friction always acts in the direction opposite to the applied force. Using this and the fact that the static coefficient of friction is different to the kinetic coefficient of...

Frictional Forces: Static and Kinetic
Newton's first law tells us that an object in motion will remain in motion, but we don't really see that on earth, do we? If you throw a ball, or push a hockey puck, these things do eventually stop. Why? To answer this we must learn...
