Flashcards in Torque Deck (12):

1

## What causes a rotation?

### When a force is not directed through the center of mass of an object

2

## What is Torque?

### An applied force that produces a rotation; product of a force and perpendicular distance

3

## How can two forces prevent rotation without being directed toward the center of mass?

### If the forces are parallel and of suitable magnitudes

4

## What is a Fulcrum?

### Fixed pivot point; where something rotates about/around

5

## What is an example of a fulcrum?

### The axis/middle of a seesaw

6

## What is best torque equal to in static equilibrium?

### Zero; Σclockwise torque= Σcounterclockwise torque

7

## What is Moment Arm Distance or Lever Arm?

### The perpendicular distance from the axis of rotation to the line of action (pivot point/center of mass to force)

8

## What is the equation of Torque?

###
τ=Fd (if F=0, τ=0)

Units= N*m

9

## Torque is a ________ quantity.

### Vector; clockwise= negative, counterclockwise= positive

10

## In order for there to be torque, force and distance must be _____________.

###
Perpendicular

11

## What is the equation for a balanced torque between two forces?

### F1d1=F2d2
