Unit 6:  Projectile Motion

d = vt                          Constant Velocity Only
v=v. + at                     Don't need d
d = 1/2 (v + v.)t          Don't need a
d = v. t + 1/2 a t^2      Don't need v
v^2 = v.^2 +2 ad        Don't need t

Free fall means an object accelerates only because of gravity. For objects near the Earth's surface, this means that acceleration = 10 m/s². When an object in free fall is thrown upward, its velocity will be zero when it reaches its highest position. When an object is thrown upward and allowed to return to its original height, its displacement will be zero.

Projectile Motion--think of the amazing basketball shot. We learned that for a projectile, horizontal velocity is CONSTANT, while vertically the object accelerates because of gravity (10 m/s^2 on earth).  To solve projectile motion problems, first split the problem into HORIZONTAL and VERTICAL parts, fill in what you know, use one part of the problem to solve for TIME, and use that time with the other part to solve for what you're looking for.

Problem Set Solutions can be found on the Physics Files Page. These Problem Sets are based on what we learn each day, and are similar to the online homework. If you are struggling with the online homework, check out the corresponding Problem Set Solution to see in detail how to approach and solve the problems.
