Question

Dao makes a table to identify the variables used in the equations for centripetal acceleration.

A 2 column 5 rows. The first column is labeled Variable with entries a Subscript c Baseline, T, r, v. The second column is labeled Quantity with entries blank, X, blank, Y.
What quantities belong in cells X and Y?

X: centripetal acceleration
Y: period
X: tangential speed
Y: radius
X: radius
Y: centripetal acceleration
X: period
Y: tangential speed

Answer 1

X = period
Y = tangential speed

(So a_c = centripetal acceleration, T = period, r = radius, v = tangential/linear speed.)
