Center of Gravity and Equilibrium

Center of Gravity

Equilibrium

• A body is in equilibrium when the sum of all external forces acting on it is zero
• The center of gravity is the point where the weight of the body can be considered to act
• In equilibrium, the center of gravity is directly above the point of support
• A body can be in stable, unstable, or neutral equilibrium depending on the position of its center of gravity

Momentum

• The center of gravity is also the point where the momentum of a body can be considered to act
• Momentum is the product of an object's mass and velocity
• A change in momentum occurs when an external force is applied to an object
• The center of gravity plays a crucial role in determining the momentum of a body

Balance Point

• The balance point is the point where the weight of a body can be considered to act
• The balance point is also known as the center of gravity
• A body is in balance when its center of gravity is directly above its base of support
• The balance point is important in determining the stability of a body

Center of Gravity

Equilibrium

• A body is in equilibrium when the net external force acting on it is zero
• The center of gravity is the point where the weight of the body can be considered to act
• In equilibrium, the center of gravity is vertically aligned with the point of support, ensuring balance
• Depending on the center of gravity's position, a body can be in stable, unstable, or neutral equilibrium

Momentum

• The center of gravity is the point where the momentum of a body can be considered to act
• Momentum is the product of an object's mass and velocity (p = mv)
• A change in momentum occurs when an external force is applied to an object, causing a change in its motion
• The center of gravity plays a crucial role in determining the momentum of a body, influencing its motion

Balance Point

• The balance point is the point where the weight of a body can be considered to act, also known as the center of gravity
• A body is in balance when its center of gravity is directly above its base of support, ensuring stability
• The balance point is critical in determining the stability of a body, as it affects its equilibrium state
