What did Daniel Bernoulli discover?

• When a fluid moves slower the pressure increases

• When a fluid moves faster the pressure drops

• When a fluid moves slower the pressure drops

What does Sir Isaac Newton's third law of motion state?

• The velocity of an object changes when it is subjected to an external force

• The pressure of an object will drop when a fluid's speed increases

• For every action, there is an equal and opposite reaction

• Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
