• Mr. Bekius climbed to the top of the Empire State Building and dropped an quarter. He watched it fall to the ground. Why does the quarter fall to the ground?

A.) Mr. B has super powersB.) massC.)accelerationD.) gravity

• When Mr. Bekius lifts 4 cows at once, he is using a contact force. Why is this an example of a contact force?

A.) Mr. B’s muscles are bigger than the cows.B.) The cows are moving.C.) He is touching the cows to lift them.D.) The cows changed position therefor they are in motion.
