Difference between centre of pressure and gravity

Which term is used to refer to the point on a body where the total pressure acts?

• Centre of Gravity

• Centre of Mass

• Centre of Buoyancy

• Centre of Pressure

What does the centre of pressure represent?

• The point where the buoyant force acts

• The point where the weight of the object acts

• The point where the net force acts

• The point where the total pressure acts

Which of the following statements is true regarding the centre of pressure?

• It is always located at the centre of the object

• It is always located at the bottom of the object

• It can change position with varying fluid pressure

• It is a fixed point on the object

Why does the position of the centre of pressure change with fluid pressure?

• Because the pressure distribution on the object changes

• Because the mass of the object changes

• Because the weight of the object changes

• Because the buoyant force acting on the object changes

How does the centre of pressure relate to stability?

• A lower centre of pressure results in greater stability

• A higher centre of pressure results in greater stability

• The centre of pressure has no effect on stability

• The centre of pressure only affects the buoyancy of the object

What is the difference between the centre of pressure and the centre of gravity?

• The centre of pressure is the point where the weight of the object acts

• The centre of gravity is the point where the buoyant force acts

• The centre of pressure is affected by fluid pressure, while the centre of gravity is not

• The centre of gravity is a fixed point on the object, while the centre of pressure is not
