Lab report 2 Acceleration and Circular Motion

Question

You have been appointed to a citizen committee investigating the safety of a proposed new ride called "The Spinner" at the Mall of America. The ride consists of seats mounted on each end of a steel beam. For most of the ride, the beam rotates about its center in a horizontal circle at a constant speed. Several committee members insist that a person moving in a circle at constant speed is not accelerating, so there is no need to be concerned about the ride's safety. You disagree and sketch a diagram showing that each component of the velocity of a person on the ride changes as a function of time even though the speed is constant. Then you calculate the magnitude of a person's acceleration. The committee is still skeptical, so you build a model to show that your calculations are correct.

You have the rotational platform shown above. You will also have an iPod and access toVernier Video Analysis. Place a temporary piece of tape on the platform with a high contrast mark on it for data collection.

Hint; Prediction: show starting from R(vector), speed and acc. magnitude are constant

plot: x vs t, y vs t, v_x vs t, v_y vs t, speed vs t

a_x vs t, a_y vs t, acc magnitude vs t

Error bar source of error

|a|=w^2R (const)

theta=wt

r vector=Rcos(wt)i vector +R sin(wt)jvector

a vector= -w^2R

calculate error percentage= (avg acc-w^2R)/w^2R *100

format of lab report 2

1) Abstract (use calibration object in abstract)

2) introduction (simply summarize question what is experiment amount)

3) prediction (already hint) make figure graph

4) procedure

5) Analysis (calculate error percentage from avg acc), at least 6 graph , see guide for more

6) conclusion ( introduce all result, analysis , calibrating obj in this)

calculate error bar, error percentage,
