Science of Baseball
Curveball: Choke the ball (wedge it down between your thumb and forefinger), and cock your wrist to the left; the ball snaps down and to the right on release. The resulting pitch should drop and curve to the left. Experiment with different speeds and spins. Screwball: Throw the ball like a curveball, but reverse the wrist action and spins.

What Is the Coriolis Effect?
2021/11/30It affects weather patterns, it affects ocean currents, and it even affects air travel. As important as the Coriolis Effect is, many have not heard about it, and even fewer understand it. In simple terms, the Coriolis Effect makes things (like planes or currents of air) traveling long distances around the Earth appear to move at a curve as opposed to a straight line.

How does temperature affect the pressure of a gas?
This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased. This means that they have more collisions with each other and the sides of the container and hence the pressure is increased. where V= Volume, P= Pressure and T= Temperature.
