Forces Calculators & Tools

Explore force calculators for Newton's laws, weight, friction, centripetal force, net force, gravity, and related dynamics problems.

5 tools in Forces. Active calculators open as full tool pages; planned tools are listed here for topic structure without linking to unfinished calculator pages.

Newton's Second Law Calculator

Active

Calculate force (F = ma), mass (m = F/a), or acceleration (a = F/m) using Newton’s second law of motion.

F = maForces

Weight Calculator

Active

Find the weight of an object from its mass and gravitational acceleration.

W = mgForces

Friction Calculator

Active

Calculate static friction, kinetic friction, inclined plane friction, coefficient of friction, normal force, or force to start motion.

F = μNForces

Centripetal Force Calculator

Active

Calculate centripetal force, acceleration, speed, radius, or mass for circular motion. Supports angular velocity and RPM.

F = mv²/rForces

Gravitational Force Calculator

Active

Apply Newton's law of universal gravitation between two masses.

F = Gm₁m₂/r²Forces
