## What Happens to Water when Heat of the Pressure does/not get Transferred into the Water

You have a finite quantity of water which you are able to compress in an apparatus. The apparatus is theoretical and cannot break, and the amount of pressure it can apply to the water is both uniform and unlimited. Additionally, ...

## Torque and Angular Acceleration

Learning Goal: To understand and apply the formula τ =Iɑ to rigid objects rotating about a fixed axis. To find the acceleration ɑ of a particle of mass m, we use Newton’s second law: , where

## Torque Magnitude Ranking Task

The wrench in the figure has six forces of equal magnitude acting on it. A) Rank these forces (A through F) on the basis of the magnitude of the torque ...

## Playing in the Field

Four children are playing in a field. The children form a line, holding hands. The player at the front of the line starts to spin around faster and faster, causing the others to run in circle, as shown in the ...

## Pivoted Rod with Unequal Masses

The figure shows a simple model of a seesaw. These consist of a plank/rod of mass mr and length 2x allowed to pivot freely about its center (or central axis), as shown in the diagram. A small sphere of mass m1 is attached to ...

## Net Torque on a Pulley

The figure below shows two blocks suspended by a cord over a pulley. The mass of block B is twice the mass of block A, while the mass of the pulley is equal to the mass of block A. The ...

## Linear and Rotational Quantities Conceptual Question

A merry-go-round is rotating at constant angular speed. Two children are riding the merry-go-round: Alan is riding at point A and Isamu is riding at point B. A) ...

## Ladybugs on a Rotating Disk

Two ladybugs sit on a rotating disk, as shown in the figure (the ladybugs are at rest with respect to the surface of the disk and do not slip). Ladybug 1 is halfway between ladybug 2 and the axis of ...

## Balancing Torques Ranking Task

A sign is to be hung from the end of a thin pole, and the pole supported by a single cable. Your design firm brainstorms the six scenarios shown below. In scenarios A, B, and D, the cable is attached ...

## Axis of Rotation and Moment of Inertia Ranking Task

Two identical uniform solid spheres are attached by a solid uniform thin rod, as shown in the figure. The rod lies on a line connecting the centers of mass of the two spheres. The axes A, B, C, and D ...
