Cohesion | The strength with which the particles of an object or fluid attract each other |
Compression | A decrease in volume produced by force |
Flow rate | The speed at which a fluid flows from one point to another |
Force | A push or pull that acts on a object, anything that changes the motion or shape of an object |
Friction | A force that opposes the sliding motion between two touching surfaces |
Gravitation | The attractions force between an object, the force that causes object so be pulled toward the centre of the Earth |
Kilopascal | A unit of pressure equal to 1000pa |
Magnetic | |
Pascal | A unit of pressure equal to 1 newton per square meter |
Pressure | The amount of force applied over a given area to an object |
Surface Tension | A property at the surface of the liquid attract each other, causing the surface to act like thin skin or membrane (paper clip lab) |
Viscosity | The resistance of a fluid to flow, the slower the flow the greater the viscosity |
