# Torque

From twisting the lid off a jar of olives, to balancing the tandem bicycle you're riding with your parole officer, torque explains it all. Learn to describe and calculate torque, the "twisting force".

The gravitational acceleration is \( g= 10 \text{ m/s}^2. \)

A cubic dice is sliding on a frictionless table. The dice is a cube with edges of length 1 cm and a mass of 30 g. A kid reaches down and gives a horizontal flick to the dice, causing it to change which face is up. What is the minimum impulse in **g~cm/s** the kid must give to the dice in order to change the face?

**Details and assumptions**

- The acceleration of gravity is \(-9.8~m/s^2\).
- You can model the dice as a perfect cube of uniform density.
- The dice never leave the table
