- A resultant force of zero.
- A force that acts on an object through physical contact.
- A region where charge will experience a non-contact electrostatic force.
- An object in it has a zero resultant force and a zero resultant moment.
- A region where an object will experience a non-contact force.
- An arrow that represents a a force. The length represents the magnitude and the arrowhead the direction in which it acts.
- A visual representation of the forces that act on an object.
- A resistive contact force that acts to oppose the relative motion between two surfaces.
- A simple mechanism that can transmit the rotation a effect of a force.
- A region where a mass will experience a non-contact gravitational force.
- A simple mechanism that can transit the rotational effect of a force.
- The application of a lubricant (such as oil) to reduce the friction that acts between surfaces. This may improve the efficiency of a system
- A region where a magnetic material will experience a non-contact magnetic force.
- The turning effect of a force, equal to the product of the magnitude of the force and the perpendicular distance from the pivot to the line of action of the force.
- The unit of a moment.
- A force that acts on an object at a distance. There is no physical contact, and instead the force acts through a field.
- For an object in equilibrium, the sum of the clockwise moments about any point on the object must equal the anticlockwise moments about that same point.
- All forces can be resolved in two perpendicular components that have the same effect as the single force.
- The single force that can replace all the individual forces acting on an object, and have the same effect.
- The single moment that has the same effect as the sum of all the other clockwise and anticlockwise moments acting on an object.
