1) Well, I play football in the summer (Canadian football, with the oblong ball you don't actually use your feet on) and I curl in the winter. Torque is very important in both sports, as is angular momentum. In football, as you release the ball you apply a downward torque with your fingers, which gets the ball spinning. That helps stabilize the ball in flight (due to conservation of angular momentum). Similarly, a torque is applied to a curling rock as it is being released to set it spinning and control its trajectory -- except in curling, the aim is not to get a straighter path but actually one that curls (hence the name of the sport).

2) Strength is actually a little tough to define exactly, but let's call it the ability to exert force or bear loads. Strength comes from your muscles acting on your ...
