Calculate acceleration and rope tension for an ideal Atwood machine. Provide Mass 1 (kg), Mass 2 (kg), Gravitational acceleration (m/s²) to compute results directly in your browser. The rope and pulley are massless, the rope is inextensible, and pulley friction is neglected. Acceleration is positive when mass 2 moves downward: g(m2−m1)/(m1+m2). Tension = 2m1m2g/(m1+m2). Numeric output uses up to 12 significant digits; floating-point rounding can occur. Common search workflows supported include "atwood machine calculator".

Practical Worked Examples for Atwood Machine Calculator
These concrete scenarios illustrate how the Atwood Machine Calculator processes baseline inputs, comparison checks, and boundary constraints.
Baseline run (Mass 1 (kg) = 1)
Mass 1 (kg) = 1; Mass 2 (kg) = 2; Gravitational acceleration (m/s²) = 9.80665. Output: Acceleration (mass 2 downward positive): 3.26888333333 m/s²; Rope tension: 13.0755333333 N.
Comparison scenario (atwood machine calculate tension)
Mass 1 (kg) = 2; Mass 2 (kg) = 2; Gravitational acceleration (m/s²) = 10. Output: Acceleration (mass 2 downward positive): 0 m/s²; Rope tension: 20 N.
Boundary & unit check (Atwood Machine Calculator)
When solving for 'atwood machine calculator', verify that Mass 1 (kg), Mass 2 (kg), Gravitational acceleration (m/s²) use consistent units and stay within the documented scope: The rope and pulley are massless, the rope is inextensible, and pulley friction is neglected. Acceleration is positive when mass 2 moves downward: g(m2−m1)/(m1+m2). Tension = 2m1m2g/(m1+m2). Numeric output uses up to 12 significant digits; floating-point rounding can occur.
How to Read and Verify the Atwood Machine Calculator Output
The output panel reports the exact result derived from Mass 1 (kg), Mass 2 (kg), Gravitational acceleration (m/s²) alongside any unit or formatting notes.
Every calculation follows the rule: Calculate acceleration and rope tension for an ideal Atwood machine. Because JavaScript uses IEEE 754 double-precision floating-point arithmetic, numeric outputs display up to 12 significant digits where applicable.
Always cross-check the displayed result against the scope note (The rope and pulley are massless, the rope is inextensible, and pulley friction is neglected. Acceleration is positive when mass 2 moves downward: g(m2−m1)/(m1+m2). Tension = 2m1m2g/(m1+m2). Numeric output uses up to 12 significant digits; floating-point rounding can occur) before applying the value to production specifications, financial models, or lab records.
