3.3.2 kinetic potential energy
... just like an object on a shelf, once caused to move off the shelf it can change the Potential energy → Kinetic energy. If an object is lifted you lose energy by doing work in your muscles and turn it into Gravitational Potential Energy as you do work against the pull of Gravity. ...

... A roller coaster car of mass m starts at rest at height y1 and falls down the path with friction, then back up until it hits height y2 (y1 > y2). An odometer tells us that the total scalar distance traveled is d. Assuming we don’t know anything about the friction or the path, how much work is done b ...

lecture 21 torque
... The sign of torque is the same as the sign of angular acceleration it causes if it were the only torque acting in the system. If two or more torques act on a rigid object, the net torque is the sum of the torques with correct sign assigned to each torque. This is analogous to Newton’s 2nd law for li ...

Air resistance acts opposite to the direction of motion of the object if there is no wind. Now we return to the example of the skydiver. The skydiver jumps out of the pla ...
