1. Work is equal to the change in kinetic energy.
W = Fd
F = ma
d = (vf2 vi2)/2a
KE = (1/2)mv2
W = Fd = (ma)(vf2 vi2)/2a = (1/2)mvf2 - (1/2)mvi2 = KEf KEi = KE
W = KE
2. W = Fcos()d
As the angle goes up, work done by applied force increases because cos()

1. For an object in UCM, tangential velocity is a constant magnitude with centripetal acceleration
being perpendicular. If a non-zero acceleration was applied parallel to the velocity, the
magnitude of tangential velocity would change.
It took approximate

Title: Angle Effects on Projectile Range
_
Abstract: The purpose of this experiment was to determine what angle would give our
projectile the greatest range. Looking at the range equation, we hypothesized that 45-degrees
would give the largest value of
