## Force

4 linksInfluence that can change the motion of an object.

Influence that can change the motion of an object.

Concepts related to force include: thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque, which produces changes in rotational speed of an object.

## Work (physics)

5 linksEnergy transferred to or from an object via the application of force along a displacement.

Energy transferred to or from an object via the application of force along a displacement.

The dimensionally equivalent newton-metre (N⋅m) is sometimes used as the measuring unit for work, but this can be confused with the measurement unit of torque.

## Angular momentum

4 linksRotational analog of linear momentum.

Rotational analog of linear momentum.

is the length of the moment arm, a line dropped perpendicularly from the origin onto the path of the particle. It is this definition,

## Newton-metre

3 linksThe newton-metre (also newton metre or newton meter; symbol N⋅m or N m ) is a unit of torque (also called ) in the SI system.

## Power (physics)

4 linksAmount of energy transferred or converted per unit time.

Amount of energy transferred or converted per unit time.

The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft.

## International System of Units

3 linksModern form of the metric system and the world's most widely used system of measurement.

Modern form of the metric system and the world's most widely used system of measurement.

The technique used by Gauss was to equate the torque induced on a suspended magnet of known mass by the Earth's magnetic field with the torque induced on an equivalent system under gravity.

## Dimensional analysis

2 linksAnalysis of the relationships between different physical quantities by identifying their base quantities and units of measure (such as miles vs. kilometres, or pounds vs. kilograms) and tracking these dimensions as calculations or comparisons are performed.

Analysis of the relationships between different physical quantities by identifying their base quantities and units of measure (such as miles vs. kilometres, or pounds vs. kilograms) and tracking these dimensions as calculations or comparisons are performed.

For example, although torque and energy share the dimension, they are fundamentally different physical quantities.

## Joule

3 linksDerived unit of energy in the International System of Units.

Derived unit of energy in the International System of Units.

In mechanics, the concept of force (in some direction) has a close analogue in the concept of torque (about some angle):

## Pound-foot (torque)

1 linksA pound-foot (lbf⋅ft) is a unit of torque representing one pound of force acting at a perpendicular distance of one foot from a pivot point.

## Moment of inertia

1 linksThe moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration.
