statics

subdivision of dynamics that deals with objects in equilibrium (forces and torques acting on an object are balanced; F_net = 0).

static equilibrium

state of equilibrium where an object is at rest.

dynamic equilibrium

state of equilibrium where an object is moving with constant velocity.

stability

How likely an object is to tip over when pushed or moved. Tipping over happens when the center of gravity is no longer directly above the base of support.

stable equilibrium

When a system returns to its original position after being displaced. The CoG does not leave the base of support.

unstable equilibrium

When a system does not return to its original position after being displaced, The CoG is outside the base of support.

neutral equilibrium

When a system returns to equilibrium but in a new position after being displaced, like a ball rolling on a horizontal surface.

torque

the tendency of a force to rotate an object to which it is applied through an axis of rotation.

• T = r * sinθ

• r = radius

• θ = angle between force and radius

• Unit = Nm (newton meters)
