Force, Mass & Acceleration Solver
Compute net force or solve for mass or acceleration. Add weight, friction, and incline components for realistic scenarios.
Result
—
Force (SI)
—
Mass (SI)

Acceleration (SI)
—
Equation Used
—
Interpretation
—
Newton’s second law uses net force. If multiple forces act, add them vectorially to find the net force that produces acceleration.
Weight (Force)
—
Weight (N)
—
Equation Used
—
Interpretation
—
Weight is the gravitational force on mass. Your mass stays the same, but weight changes if gravitational acceleration changes.
Normal Force (N)
—
Friction Force
—
Equation Used
—
Interpretation
—
On a flat surface without extra vertical forces, normal force is approximately N = m·g. On inclines or with extra loads, use the Incline tab or enter a normal-force override.

Equation Used
—
Interpretation
—
On an incline, weight splits into parallel and perpendicular components. Friction uses μ times the normal force, so changing angle changes both the downhill pull and friction.

Table mode uses F = m·a in SI, then converts to your selected force unit. Use it for quick comparisons and sanity checks.
