☛ The perpendicular or normal force acting on a body or surface is called thrust.

• It is a vector quantity.

• SI unit of thrust is kg m/s².

• CGS unit of thrust is dyne (10⁶).

➤ Pressure :-It is defined as thrust acting per unit area.It is the effect of thrust.

• It is a scaler quantity.

• pressure is inversely proportional to area.

• SI unit of pressure is N/m² = Pascal (pa)

➤ Density :-It is defined as mass per unit volume.

• Density = mass/volume.

• SI unit of density is kg/m³.

• CGS unit of density is g/cm³.

• Density is a property of material.
