Question

Hello, this is my laboratory procedure and purpose and I have to do a formal lab about it. I don't really know how to start my objective. Can someone please help me out. It cannot be two sentences, at least a paragraph so I can have an idea of how to start. Thank you Name(s) Group # Date LAB #3: UNIFORMLY ACCELERATED MOTION-Abridged OBJECTIVES To study the motions of two systems that have constant acceleration. One that is in free-fall and one that has a smaller acceleration EQUIPMENT: Equipment Needed Oty Equipment Needed Picket Fence Board 1 Atwood's Machine Photogate /Pulley System Mouse Pad 1 Pasco Mass and Hanger Set Double-V Clamp Table Clamp w/Rod 1 Ruler Linear Graph Paper on Front Desk DataStudio on computer SAFETY REMINDER THINK SAFETY Follow all safety instructions. Keep the area clear where you will be working and walking. ACT SARELY BE SAFE! INTRODUCTION In this lab you will be using the computer to take data for two experiments, the "picket fence" board as it falls through a photogate, and an accelerating Atwood's machine. This data will then be graphed and analyzed. PROCEDURES Answer all of the questions on this handout When an object has a constant acceleration, its position, "x", depends on its acceleration, "a", the time it has been moving, "", its initial position,"", and its initial velocity, "o". That is X-Xo+Vot+(12) at2 . It velocity, "v", depends on its acceleration, "a", the time it has been moving, "", and its initial velocity,"w”. That is We can see that if the velocity is graphed as a function of the time, the slope will be the acceleration

Explanation / Answer

We can start right from the basic motive of such an experiment. It is mainly to 'visualise' the kinetic equations of motion. The equations of motion mentioned in the picture are the basic kinematic equations of motion which you will be putting into use to measure parameters like distance, acceleration, time and velocity.

As you would have noticed, the picket fence is nothing but a sheet of paper wtih alternate dark patches of fixed length, let's call this 'B mts'. Whenever the photogate sees a black patch it records it and the moment it sees the next black patch, it gives you the time between the two black patches that has passed.

Now, during this time, say t. the total length that has been covered is the length of the black patch B and after that the length of the white patch, say W mts. Now the moment it sees the next black patch, that is where the white patch ends, the data interface/computer interface will show you a time. In this time the total length that has been covered is W+B mts.
Another thing to note is, te picket fence is free falling, that is it is falling under the action of gravity or graviational acceleration g( 10 m/s^2).

Now, you have the distance of W + B mts, acceleration g, the initial velocity with which the fence is dropped is 0 m/s, you can caluclate the final velocity, time taken(photogate will give this), total length is the length of the picket fence.

Say, for example, you want to calculate the acceleration with which it is falling (we already know it is g) but just to get the hang of things...

you need to solve two simultaneous equations of motion

2*a*s = V^2 - U^2 and

V = U +a*t

You know s through the length of the picket fence, U is 0m/s

In such a way you can change the length, initial velocity etc to visualise these equations and plot your points which will reflect the equations of motion.

LIke, V=U+a*t, is of the form of Y=mx+c.
