Accelerated Motion • Motion with constant acceleration is what we will mostly look at in this class • Example: • Gravity: Objects fall to the ground at a constant 9.8m/s² (neglecting air resistance)
Galileo Galilei • Galileo was the first to describe gravity and how it acted. • He discovered the ideas behind how displacement, velocity and acceleration are all related to one another. • He developed the kinematic equations
Kinematics • There is a set of equations used to govern objects motion with constant acceleration. These equations are called the kinematic equations…
Kinematic Variables • There are 5 different variables when considering a problem to use the kinematic equations. • Vf = Final Velocity • Vi = Initial Velocity • a = Acceleration • t = time • d = displacement
Kinematic Variables • When solving problems using the kinematic equations: • 3 of them must be know • 1 is not needed • 1 is what your trying to find
