Study Notes
Center of Mass
- The point where the weight of a body appears to be concentrated is known as the center of mass.
Types of Equilibrium
- Static Equilibrium: A state where the body is at rest due to no net force acting on it.
- Stable Equilibrium: Characterized by a body that cannot be easily toppled down; any small displacement will result in forces that return the body to its original position.
- Unstable Equilibrium: A body in this state can be easily toppled down, as even small displacements lead to an increase in potential energy, causing the body to shift position.
Conditions of Equilibrium
- The condition of equilibrium requires that the vector summation of all forces acting on the system must equal zero.
Body Characteristics
- A solid body in which deformation is negligible or zero is referred to as a rigid body.
