Forces Glossary

The overall force acting on an object after all forces have been combined.

defined as the force required to accelerate a mass of one kilogram by one meter per second squared. Mathematically, it can be expressed as 1 kg·m/s². It's like a cosmic equation that quantifies the push or pull on an object, allowing us to measure the strength of forces in the universe!

An object remains at rest or moves with constant velocity unless acted upon by a net external force.

The net force on an object equals its mass multiplied by its acceleration (F=ma).

For every action force, there is an equal and opposite reaction force.

A force that acts without physical contact between objects.

A direction that is perpendicular to a surface

The support force exerted by a surface, acting perpendicular to it.
