episode 6: The APsolute RecAP: Physics 1 Edition - Objects in Freefall
Objects that are in free fall are objects moving in one dimension, just doing so vertically. We ignore air resistance unless told otherwise, and we don’t worry about what happens before and after the object is in freefall (1:15). If on earth, the acceleration we should use is -9.81 m/s2.(1:50) Episode 6 recaps 3 key aspects of free-fall problems (4:47). Throw a ball into the air at 30 m/s to follow along with our example problem (5:49).
The Question of the Day asks:(8:38) A t-shirt is launched straight upward from a canon at a basketball game, what is the t-shirt’s acceleration at the peak?
