Activity 7: Conservation of Energy- Moment of Inertia

Question 1

What did you do in Activity 7?

Answer 1

Moment of ineria was calculated using a ring, disk, and sphere after measuring their weight and radii. Max velocity for each object was calculated and measured.

Question 2

velocity of a ring

Answer 2

√(gh)

Question 3

Velocity of a Disk

Answer 3

√(4/3hg)

Question 4

Velocity of a Sphere

Answer 4

√(10/7hg)

Question 5

Moment of Inertia (Ring)

Answer 5

I=mr²

Question 6

Moment of Inertia (Disk)

Answer 6

I=1/2 mr²

Question 7

Moment of Inertia (sphere)

Answer 7

I= 2/5 mr²
