What is the purpose of a free fall Lab?
The purpose of this laboratory activity is to measure the acceleration of a falling object assuming that the only force acting on the object is the gravitational force.
What is a picket fence in physics?
The Photogate has a beam of infrared light that travels from one side to the other. It can detect whenever this beam is blocked. You will drop a piece of clear plastic with evenly spaced black bars on it, called a Picket Fence.
What is the acceleration of the picket fence?
The value of the gravitational acceleration is approximately 9.8 m/s2. For You To Do. In this experiment you drop a “picket fence” (a clear plastic strip with uniformly spaced opaque bands) through a photogate.
What is your conclusion about force?
Conclusion: It might be concluded that whenever the direction of force is in the direction of motion than the speed of object increases and whenever it is opposite to the direction of motion it speed decreases. And force always need not change state of motion.
What conclusions can you make regarding the acceleration of the basketball during the initial fall and between the first and second bounces?
What conclusions can you make regarding the acceleration of the basketball during the initial fall and between the first and second bounces? After the first bounce, the ball is moving upward toward the motion sensor and slowing down be- fore it speeds up again and bounces the second time.
What is the purpose of the picket fence lab?
Conclusion. The purpose of this lab was to measure the acceleration of a free falling object by using the slope of a velocity vs. time graph. If we drop the picket fence from the same height every time then the photogate will read the slope at 9.8 every time.
Would throwing the Picket fence upward change any of your measurements?
Conclusion. Throwing the Picket Fence downward instead of dropping it would change the graphs and values because a force other than gravity acted on it. Throwing it upward would also change them because gravity is acting against it and it would eventually fall back. This experiment showed us that we were correct.
Would throwing the Picket Fence downward?
Conclusion. Throwing the Picket Fence downward instead of dropping it would change the graphs and values because a force other than gravity acted on it. Throwing it upward would also change them because gravity is acting against it and it would eventually fall back.
What is the conclusion of force and motion?
When you bounce a ball eventually it will stop bouncing when does the energy go?
When a basketball bounces (without being pushed down), it does not go all the way back up to its original height, as shown in Figure 2 below. This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely. The energy has left the ball!
What are the action Reaction Force that happens in playing basketball?
The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
What factors do you think affected the movement of the falling objects?
Accordingly, falling is affected by a variety of factors, and the controllable part is the object’s surface area, angle, and weight. The combination of these controls and physics rules has made parachuting and freefalling possible.
Does mass affect acceleration due to gravity?
“What are the factors that affect the acceleration due to gravity?” Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.
What is the purpose of the picket fence free fall lab?
The purpose of the Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth. During free-fall the only force that should be acting upon the object is the earth’s gravitational pull (9.8 m/s/s), therefore the velocity of the object should always equal 9.8 m/s/s.
Why does a picket fence not fall down?
This is due to the fact that the fence is fighting gravity as it is thrown upward, as opposed to free falling because of the pull of gravity. The purpose of the Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth.
How fast does a picket fence fall?
In this lab the picket fence was dropped repeatedly through a photogate connected to Logger Pro, which allowed the fence’s acceleration and velocity to be recorded and graphed. The results of the experiment confirmed the theory that objects will fall with a constant acceleration equal to g (9.8 m/s/s).
What will the photogate read when I drop the picket fence?
If we drop the picket fence from the same height every time then the photogate will read the slope at 9.8 every time. Great Job! 3rd Hr. For our trials we stayed around 9.7. Which was just under what we stated in our hypothesis. The minimum number of acceleration was 9.7475 and our maximum number was 9.7756. Our average number was 9.75488.
