Question

Mrs. Newman’s class decides to perform an experiment during a class connect session to determine how long it takes different objects to hit the floor when dropped from the student’s desk. Each student dropped three notebooks, one weighing 0.5 pound, one weighing 1.0 pound, and one weighing 2.5 pounds. What would you predict about the times it took for each of them to hit the floor?
a) The 0.5lb notebook would hit the floor first
b) The 0.5lb notebook would hit the floor last
c) The 2.5lb notebook would hit the floor first
d) All notebooks would fall at the same time
e) All notebooks would remain suspended in the air

Answer 1

D, all notebooks would hit the floor at the same time. The time it takes to hit the floor is independent of their weight, but rather dependent on the acceleration of gravity. Since gravity is constant, they will all hit the floor at the same time.

Answer 2

the correct answer would be D because they all have the same gravitational pull
