Hi all
While doing a demonstration involving showing free fall, one of my st=
udents asked if the I threw the ball down would it still be in free =
fall? I was like it is still in free fall even if you throw it down.=
Then he asked but the acceleration is more than g, you have acceler=
ated the ball to throw it and there is the earth's gravitational acce=
leration so if you add them like vectors it is larger than g.
I was like no it's not larger than g because it is in free fall. Whi=
ch I have decided was probably not a great explanation. I was like t=
he acceleration is constant...
How better to answer the student?
Cheers
Tina
