We walk here, we walk there, we walk everywhere. Maybe you’re headed to work or to lunch in a busy city. You’re expending energy, and the exercise is good for you. But what if, on top of that, we ...

Solve a basketball jump physics problem by tracking how mechanical energy changes from takeoff to peak height. This video explains kinetic energy, gravitational potential energy, and energy ...

Suppose we consider the incline to be smooth. In this case, there is no work done on the system by non-conservative forces. Consider the simulation results below of the block sliding on a smooth ...
