Question

A student is investigating gravity and falling objects. She drops three balls and times how long it takes each ball to hit the ground. What is the most likely source of error?

(1 point)

She used balls that are different sizes.

She did not measure the circumference of the balls.

She dropped the balls from different heights.

She did not measure the mass after the balls hit the ground.

Answer 1

Answer:C

Explanation: This is because the time for the 26 gram ball was around 6 seconds longer which if they were dropped at the same height then the ball with more mass would fall faster because of its gravitational pull.

Answer 2

The most likely source of error might be she dropped the balls from different heights. Option C is correct.

What is gravitational acceleration?

• It is the acceleration of the falling object {vacuume) due to gravity.

• The gravitational acceleration is a constant value, it is equal for every falling object in a vacuum regardless of its mass or size.

• It only depends upon the height of the object.

Therefore, the most likely source of error might be she dropped the balls from different heights.
