Useful Equations with FreeFall:
remember: a = g and x = y. Different variables for freefall but you may use whichever.
g = [(vo-vf)/ 2]t
vf = vo + gt
y = [(vo+vf)/2]t
y = vot + (1/2)gt^2
vf^2 = vo^2 + 2gy
Remember! You can use algebra to rearrange the variables to solve for what you need!
Want a fantastic explanation of free fall at your very own fingertips?!
Well go to http://www.physicsclassroom.com/class/1dkin/u1l5a.cfm and prepare to learn a whole bunch about free fall!
Hi, how have you been? I have been good. This year I am taking physics and it is actually very interesting! One thing that has shocked me is that a pencil dropped at the same height as a bowling ball will hit the ground at the same time! Weight does not influence something called Free Fall. Any object falling because of gravity will fall at a constant acceleration of 9.8 m/s/s. The velocity will increase as time increases. Some variables that I have to learn for free fall are g which stands for acceleration and the unit is m/s/s. We also have to learn vo and vf which stand for initial velocity and final veocity, respectfully, and the unit for those are m/s. Distance is also needed for free fall because we need to know from what height the object is falling. The variable for that is y and m is the unit used. Lastly, we use t for time and use s as the variable. I know this might sound a bit overwhelming but the more you practice the equations the easier they get! Okay well I will ee you soon!
