Two balls that look the same, but have different masses are dropped at the same time from the top of the ladder. Which ball will hit the ground first?

Both pieces of paper will hit the ground at the same time because the acceleration due to gravity is a constant (Stays the same).

The ball with the most mass because it has less air resistance slowing the paper.

The ball with the most mass because it has more air resistance slowing the paper.

Which equation would you use to find the acceleration of an automobile whose speed decreases from 100 m/s to 5 m/s in 20s?

(5m/s-100m/s) / 20s = -4.75m/s 2

(100m/s-5m/s) / 20s = 4.75m/s 2

(100m/s+5m/s) / 20s = 5.25m/s 2

Two students noted that a horse's acceleration was -30km/s 2 . Student 1 said, "That can't be right. You can't have a negative acceleration." What would you tell student 1?

You can have negative acceleration. It means the horse's speed is decreasing.

You can have negative acceleration. It means the horse's speed in increasing.

They must have put the numbers into the calculator wrong.

They mixed up the initial and final velocities.

Two students noted that a horse's acceleration was -30km/s 2 . Student 2 said, "That can't be right. You can't have s 2 ."

I disagree with student 2. The s 2 comes from km per second (speed) divided by time (s). km/s/s =km/s 2

I agree with student 2 because the unit for speed is km/s

I disagree with student 2 because the units for acceleration is km/s/s.

I agree with student 2. Acceleration is velocity over time, so time is only in the equation once

A group of students dropped a ball and used a video recording to measure the distance and time for each frame. They completed this data table using their results. Was the acceleration for the ball constant?

No. The acceleration was 8.9 m/s/s for frames 5 and 6, but was different for every other frame.

Yes. The acceleration was 0.03s for each frame.

Yes. The acceleration was 8.9 m/s/s for frames 5 and 6.

No. Frame 8 was accelerating while the others were decelerating.

A group of students dropped a ball and used a video recording to measure the distance and time for each frame. They completed this data table using their results. Would you expect to see a pattern in which the acceleration increases in each frame?

No. Gravity on Earth is, for the most part, constant.

Yes. The acceleration was 0.03s for each frame.

Yes. Gravity on Earth is not constant.

No. Only frames 4 and 5 are constant.

A group of students dropped a ball and used a video recording to measure the distance and time for each frame. They completed this data table using their results. Why might you want to exclude the acceleration to frame 3?

The ball moved such a small amount, it is hard to measuere

The ball is moving so fast, it is a large blur and is difficult to determine the middle of the ball.

If the ball impacted with the surface, it might be decelerating.

A group of students dropped a ball and used a video recording to measure the distance and time for each frame. They completed this data table using their results. Why might you want to exclude the acceleration to frame 8? Choose all that apply.

A group of students dropped the ball and used a video recording to measure the distance and time for each frame. They completed this data table using their results. Is it always OK to remove data if it does not support your claim?

Removing data from your data table is not OK, but leaving some data out of the averages is acceptable if you can show that the data includes measurement errors. You must also describe what you did and why in your report.

It is OK to remove data just because it not supports your claim.

Two pieces of paper that are the same size and mass are dropped at the same time. One is flat and the other is crumpled into a ball. Which piece will hit the ground first?

The crumpled paper because its shape allows for less air resistance slowing the paper.

The flat paper because its shape allows for less air resistance slowing the paper.

Both pieces of paper will hit the ground at the same time because they are the same mass.
