Forces & Momentum
Force, friction, inclined planes, tension, momentum and collisions.
- Centre of Mass Calculator The balance point of up to four masses at given positions.
- Elastic Collision Calculator Velocities after a head-on elastic collision between two objects.
- Force, Mass and Acceleration Calculator (F = ma) Newton’s second law: find force, mass or acceleration from the other two.
- Friction and Coefficient of Friction Calculator Find friction force, the coefficient of friction or the normal force from the other two.
- Impulse Calculator Impulse from a force over a time or a change in velocity, with the average force and the velocity change.
- Inclined Plane Calculator Forces on a mass on a slope, whether it slides, how fast it accelerates and the force needed to push it up.
- Inelastic Collision Calculator Velocities after a head-on inelastic collision, with the kinetic energy lost.
- Momentum Calculator Find momentum, mass or velocity from the other two.
- Net Force Calculator Add up to four forces at any angle into one resultant force, with its direction and the acceleration it causes.
- Normal Force Calculator The force a surface pushes back with, on the flat or a slope, with any extra push or pull.
- Tension Calculator Rope tension for a hanging load, a load on two ropes, or two masses over a pulley.
- Weight Calculator (Mass × Gravity) The weight of a mass as a force, on Earth, on other planets or under any gravity.
