Projectile Motion
... • Gravity, being a downward force, causes a projectile to accelerate in the downward direction. • The force of gravity could never alter the horizontal velocity of an object since perpendicular components of motion are independent of each other; – vertical force does not effect a horizontal motion. ...

Notes for Class Meeting 3: Consequences of Newton`s Laws
... As an aside, this is a good place to discuss dimensional analysis. When a physicist does not know how to calculate some quantity exactly, he or she can still get an estimate by what is known as dimensional analysis. The technique is to list all of the variables that can contribute to a result and th ...
