Mechanics & heat
Use classical mechanics and constant-property heat formulas. Work stays in your browser tab.
Kinetic energy calculator
Calculate classical translational kinetic energy for a mass and speed.
Gravitational potential energy
Estimate gravitational energy change at a chosen constant acceleration.
Linear momentum calculator
Find one-dimensional linear momentum.
Force from mass and acceleration
Calculate net force using Newton’s second law.
Mechanical work at an angle
Calculate work done by a constant force along a straight displacement.
Spring energy calculator
Estimate stored elastic energy and force for a linear spring.
Centripetal acceleration
Find the radial acceleration and force for uniform circular motion.
Hydrostatic pressure
Estimate pressure increase below a fluid surface at a stated density.
Pipe average flow velocity
Convert volumetric flow and inside diameter into average pipe velocity.
Sensible heat energy
Estimate energy to change a material temperature without a phase change.
