Free Fall Laboratory Gizmo Answers

The Free-Fall Laboratory is one the science materials you can find on Gizmo. This material allows you to calculate the motion of an object in free fall. Furthermore, it works to investigate the motion of an object when it falls to the ground.

After learning about the Free-Fall Laboratory, you will need to take the Free-Fall Laboratory test on Gizmo. Certainly, you should answer all the questions correctly to gain a high score. If you’re accidentally looking for the Free-Fall Laboratory answers, you can dive into our post to find the answers. Here you go!

The Free-Fall Laboratory Gizmo Answers

There are some sections on the Free-Fall Laboratory test on Gizmo. To make it easier for you to get the Free-Fall Laboratory answers, we will show the correct answers that we will highlight in bold font. Unfortunately, we cannot show you the full answers of the Free-Fall Laboratory, instead we will give you some of the Free-Fall Laboratory answers.

Warming Up

1. You need to click the ‘Play’ button   to   release   the   shuttlecock.   How   long   does   it   take   to   fall   to   the   bottom?   T= 0.90 s
2. You need to choose the ‘GRAPH’ tab.   The   box   labelled h (m) should   be   checked, displaying   a   graph   of   height   vs.   time.   What   does   this   graph   show? The shuttlecock is accelerating downward.
3. You need to turn   on   the v (m/s) box   to   see   a   graph   of    velocity     vs.   time.   Velocity     is   the   speed   and   direction   of   the   object.   Velocity   is   also   referred   to   as    instantaneous   velocity.   Because   the   shuttlecock   is   falling   downward, its   velocity   is   negative.
   Does the velocity stay constant as the object drops? No
4. You will need to turn   on   the  a (m/s/s) box   to   see   a   graph   of    acceleration     vs.   time.   Acceleration   is   the   rate   at   which   the   velocity   changes   over   time.   What   does   this   graph   show?
   Shown that the shuttlecock accelerates, then starts to steady its velocity with a slight deceleration at the end.

Activity A – Falling Objects

Question: What factors affect how quickly an object falls?

1.  Observe:   Drop   each   item   through ‘Air’    from   a   height   of ‘3 meters’.   Record   how   long   it   takes   to   fall   below.   For   the   tennis   ball, you may need to try   to   click the ‘Pause’ button  when   it   hits   the   ground.

2. Form a hypothesis:   Why   do   some   objects   fall   faster   than   others?

Some objects accelerate faster due to their mass and shape

3. Predict:   A   vacuum   has   no   air.   How   do   you   think   the   results   will   change   if   the   objects   fall   through   a   vacuum?

Object will fall at the same time due to the acceleration

4. Experiment:   On   the ‘Atmosphere’ menu, select ‘None’.   Drop   each   item   again, and record   the   results   below.

5. Analyze:   What   happened   when   objects   fell   through   a   vacuum?

All   objects   reached   the   same   height   inside   the   vacuum   at   the   same   time,   in   some   cases   the   object   bounced.

6. Draw   conclusions:   Objects   falling   through   air   are   slowed   by   the   force   of    air   resistance.   Which   objects   were   slowed   the   most   by   air   resistance?   Why   do   you   think   this   is   so?

The   lighter   objects   such   as   the   cotton   balls   were   slowed   the   most   since   they   do   not   have   the   mass   to   counter   the   weight   of   the   air, like   heavier   objects   like   the   rock   carried.

What Is the Aim of Free-Fall Laboratory Learning?

The aim of the Free-Fall Laboratory is to measure the acceleration of a falling object assuming that the only force acting on the object is the force of gravity. To measure the acceleration that is caused by the force of gravitational, some questions should be answered:

• Is the acceleration constant?
• If the acceleration is constant, what is the value of the acceleration?

For this laboratory activity, the Free-Fall Adapter will calculate the time of fall for steel balls of different mass and sizes. With the use of a meter stick, you will calculate the height the ball falls directly.
