## Force

Influence 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)

Energy 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

Rotational 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

The 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)

Amount 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

Modern 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

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

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):
