`T = (m*g)+(m*a)`

Enter a value for all fields

This Tension equation is used to compute the tension(**T**) in a string that is suspending a mass(**m**) below it.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**m**) Mass - (
**a**) Acceleration due to other forces - (
**g**) Acceleration due to gravity

**Tension(T)****:** The equation returns the tension(**T**) of a string in Newtons. However, this can be automatically converted to other force units via the pull-down menu.

Tension tells us how much force is being applied to a pulling medium such as a rope. An elementary equation tell us that Tension can be calculated between the relationship of mass, gravity and acceleration:

where:

- T is the tension
- m is the mass of a hanging object
- a is the acceleration (up or down) in which the object is moving
- g is the acceleration due to gravity

If the mass is moving upwards then you should list your acceleration as a negative force since the force of gravity is counted as being positive.
