Question

Newton's Laws Science Question?

1. You own a high speed digital camera that can take a picture every 0.5 seconds. You decide to take a picture every 0.5 seconds of your physics teacher as she drops a watermelon off the top of the school. After you develop and analyze the pictures, you realize that the distance the watermelon falls from the teacher in each new picture is what?
A) the same in each picture

B) gradually less in each picture

C) gradually more in each picture

D) proportional to the mass of the watermelon

Answer 1

The watermelon falls under the influence of gravity. We know that the downward force on the watermelon will be
\[F=m\times g\]
We know that
\[F= m\times a\]
a= acceleration
so
\[ma=mg\]
\[a=g\]
So the acceleration will be same for all the watermelons, what do you think should be the answer?
