The basic four equations for physics Fantastic Four The basic four equations for physics

The Fantastic Four Equations for all uniform acceleration d= displacement(m) or distance a = acceleration(m/s2) t= time(secs) Vf = final velocity(m/s) Vi = initial velocity(m/s) vf = vi + at d = vit + ½ at2 vf2 = vi2 +2ad d= ½ (vf + vi)t

wtf W = What are they asking for?? T = Tell me what you know!! F = Find the Formula solve the problem

Ex: If a car travels with a velocity of 2. 0m/s at a rate of +4 Ex: If a car travels with a velocity of 2.0m/s at a rate of +4.0 m/s2 for 2.5 secs. What is the final velocity? vf = vi + at

Ex: A car starting from rest accelerates at +6. 1m/s2 for 7. 0 secs Ex: A car starting from rest accelerates at +6.1m/s2 for 7.0 secs. How far does this car move? d = vi t + ½ at2

EX: An airplane must reach a velocity of 7. 0m/s for takeoff EX: An airplane must reach a velocity of 7.0m/s for takeoff. If the runway is 1.00km long, what is the plane’s acceleration? vf 2 = vi2 + 2ad

Ex: What is the displacement of a train as it accelerates from 11m/s to 33m/s in .333 minutes? d = ½(vf + vi)t

Free Fall problems When air resistance is ignored all objects fall at the ___________acceleration http://www.youtube.com/watch?v=5C5_dOE yAfk http://www.youtube.com/watch?v=7eTw35Z D1Ig The acceleration due to gravity is _________. Why is it negative? Since it is moving at a constant or ________acceleration__________

Things to Remember when working Free Fall Problems!! The d is always a __________value. Why? Vf is always a _________value. Why? So, when use vf2 = vi2 + 2ad and you determine vf it will a always be_________ in a free fall problem.
