Translational (a) v. Angular Acceleration (α) Experimentation
Translational (a) v. Angular Acceleration (α) Experimentation
Choose an object that will roll.
Create a list of variables that will fit into these two categories.
These variables will affect the translational and angular accelerations (α):
These variables will NOT affec the translational and angular accelerations(α).
Given a set angle, devise a means of measuring both the angular (α) acceleration (rad/sec^2) and the translational acceleration (m/s^2) of your object.
Collect data for no fewer than 5 angles of your ramp.
Create a graph of your data plotting the angular acceleration (α) on the x-axis and translational acceleration (a)on the y-axis.
From your graph,
determine the numeric slope of your linearized data,
determine the units for the slope of your data.
from the base expression y=mx+b,
Constant angular velocity (ω).
Constant tangential velocity (v_T).

Zero the position of the cart and ensure that motion to the right is positive. On a level track, give the cart a gentle push.
Using a level rotational sensor, give the bar a gentle push. Zero the angle and ensure that the direction the counter-clockwise direction is positive.
