- IM
- Acronym for Inspection and Maintenance Programs
- I/M
- Acronym for Inspection and Maintenance
- IMBA
- Acronym for International Mountain Bicycling Association which is an organization dedicated to protect mountain bike trails
- Imbalance
- A lack of balance due to uneven weight distribution. Improper wheel balance due
to uneven weight distribution on the tire and wheel assembly is one of the most
common causes of vibration. When one side of the tire and wheel assembly is heavier
than the other, centrifugal forces try to throw the heavy area outwards as the
wheel turns.

- Immunize
- To remove small particles of iron or grit from the surface of stainless steel by pickling in an acid solution.
- Impact absorber
- An impact-damping element located between the bumper and bumper mounting to keep impact energy from being transferred into the car body
- Impact break
- A rupture to a tire resulting from the shock of striking a chuck-hole, rock, curb, etc. and not caused by cutting.

- Impact damage
- Damage that has been caused to the wall of a tire by contact with a curb or deep pothole, etc.
- Impact pipe
- A simplified version of an Impact absorber
- Impact resistance test
- A determination of the resistance to breakage by flexural shock of plastics, as indicated by the energy extracted from standardized pendulum-type hammers, mounted in standard machines, in breaking standard specimens with one pendulum swing
- Impact-resistant
- Something that is stiffened (to a certain degree) to resist the force of a collision
- Impact screwdriver
- A tool which features a mechanism that converts the impact from a hammer into a powerful torque for loosening (or tightening) threaded fasteners. Also called impact driver.
- Impact sensor

- Impact socket
- A heavy duty socket for use with air or electric power impact tools. Impact sockets are designed to stand up to the extreme stress of these tools and can be used in combination with special impact accessories such as extensions, universal joints, and adapters. These accessories are also designed to withstand the stress of air or electric power impact tools
- Impact swivel ball universal joint
- The swivel ball type universal joint is the most common type for use with impact sockets
- Impact test
- An experiment to determine the amount of energy absorbed in hitting an object at high velocity.

- Impedance (Z)
-
- Opposition in an electrical circuit to the flow of an alternating current that is similar to the electrical resistance to a direct current.
- The vectorial sum of both resistance and reactance in an electric motor; total opposition to current flow, measured in ohms. Z is the impedance symbol
- Any device that introduces electrical opposition in the form of resistance, reactance, or both.
