net force

net force

combined sum of all forces pushing or pulling on an object

newton first law

An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.

newtons second law

The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body.

newtons third law

for every action (force) in nature there is an equal and opposite reaction

inertia

the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its velocity to change

coeffiecient of friction

the ratio between friction force and normal force

contact force

any force that occurs as a result of two objects making contact with each other

equilibrium

a state in which opposing forces or influences are balanced.

field force

the region of space surrounding a body, such as a charged particle or a magnet, within which it can exert a force on another similar body not in contact with it

kinetic friction

the force that acts on an object in motion, opposing its movement.

net external force

the vector sum of all the forces acting on a system from the outside of the system.

static friction

a force that keeps an object at rest.

universal forces

gravity, electromagnetism, nuclear
