The last time I looked at this projectile motion lab, I was confused. My different methods for measuring the launch speed of the ball were not even close to being consistent. So, I am bringing out the ...

Suppose you throw some object near the surface of the earth. If the only significant force on the object is the constant downward gravitational force, we call this "projectile motion." Yes, that ...

As the name suggests, horizontal motion occurs when the object is thrown horizontally, meaning it starts with zero vertical velocity. The only force acting on the object is gravity, causing it to ...

The oculomotor system is a useful model for the study of purposeful movements. Rotations of the eyes are produced by three pairs of extraocular muscles that are innervated by motor neurons from the ...

Which long jumpers will leave the London Games with a medal and which with just a memory depends, of course, on the horizontal distance they cover. Paradoxically, however, vertical velocity (the speed ...
