A. = Force / mass

B. = Acceleration / Radius of large disk

C. = Acceleration / Radius of Smart Pulley ----- NOT this

D. = m(g-a)R

2. What is the second method of finding I (rotational inertia)?

A. The slope of the torque versus angular acceleration plot ------ NOT this

B. 1/2 M R2

C. 1/3 M R3

D. M R

3. The data table has a some columns. How will you calculate torque?

A. m (g-a) R

B. M (g-a) R ---- NOT this.

C. Acceleration / Radius of large disk

D. (m2-m1) g

E. m g

Explanation / Answer

1.

The relation between angular acceleration and linear acceleration is,

   = linear acceleration / radius of the object

Option: B is correct.

2.

The general expression for the rotational inertia is,

I = MR2

The second method to determine the rotational inertia is,

I = (1/2) MR2

Option:B

3.

The torque is calculated as follows;

  Torque = I* = m(g-a) R

Option: A
