Mechanical Equilibrium

a push or a pull exerted on an object
Net Force
the overall force on an object when all the individual forces acting on an object are added together.
a quantity with magnitude and direction.
Vector Quantity
quantity that needs to have both amount and direction defined
Scalar Quantity
a quantity that has mangutude but no derection
Mechanical Equilibrium
the state of an object or system of objects for which any impressed forces cancel to zero and no acceleration occurs
Equilibrium Rule
for any body in mechanical equilibrium the vector sum of the forces on it are zero, {F=0
Support Force
Upward force that balances gravity. (also known as normal force)
a vector that is the sum of two or more other vectors
