Simulating Gravitational Attraction
See your handout for guidance but this link will help us explore the law of gravitation.
National Football League does Physics!!
Newton's three laws are done here but let's focus on the one on projectile motion for this lesson.

The Law of Gravitation
Newton's Law of Gravitation accounts for the effect between two masses and the distance between those masses. Some things to note: masses must be in kilograms and the distance between the two masses must be in meters (m). There will be scientific notation numbers to work with so remember to use the EE or EXP on your calculator.
Simulating Projectile Motion
Your handout will guide you but this link will help us explore projectile motion. For example, what determines "hang time", range, and the height of the projectile?
Formulas for projectile motion
In most cases of projectile motion, one component of the velocity (horizontal or vertical) does not change. This makes solving the problems much easier. To the left you will find the basic formulas needed (there are two) and neither one of these is new to us.
