newtons laws and forces

newtons

the SI of measurement of force

Inertia

Tendency of an object to resist changes in its state of motion depends on how much mass an object has. 

weight

force of gravity acting on an object and all the forces acting on it

tension

Pulling force exerted by a string, rope, or cable when it is stretched

unbalanced forces

results in a net force acting on an objet, causing it to accelerate

free body diagrams

a simplified diagram that represents an object and all the forces acting on it

static friction

force that opposes the start of movement between two surfaces in contact

kinetic friction

the force thay opposes the motion of two surfaces that are sliding past each other. It is typically less than static friction and acts in the direction opposite to the motion

coefficient of friction

a dimensionless number that quantifies the frictional properties of a material pair; used to calculate the force of friction and is different for static and kinetic

net force

represents the overall force experienced by the object; calculated by finding the sum of all the forces acting on an object
