Tension Calculator

Find the tension in a rope holding or lifting a mass.

Mass

Upward acceleration (m/s²)

Gravity (m/s²)

Tension (N) 78.48

Formula: T = m(g + a)

Step-by-step with your numbers:

1. Values used:

2. Mass = 8

3. Upward acceleration = 0 m/s²

4. Gravity = 9.81 m/s²

6. Tension = 78.48N

Did we solve your problem today?

Tension is the pulling force transmitted through a rope, cable or string.

The math behind it

For a hanging mass, T = m(g + a). At rest (a = 0) tension just equals the weight; lifting (a > 0) increases it.

8 kg held still → tension 78.5 N.

What if the mass accelerates downward?

Use a negative acceleration, which lowers the tension.
