Understanding Newtonian and Non-Newtonian Fluids

The video explores Newton's laws, focusing on reactions and fluid behavior. It introduces non-Newtonian fluids, like oobleck, which change viscosity under pressure. The video discusses practical applications, such as body armor, highlighting advancements in safety gear using non-Newtonian properties. The potential for flexible, yet protective clothing is examined, showcasing innovations in materials science.

What did Isaac Newton believe was responsible for the apple falling from the tree?

• Wind

• Gravity

• Friction

• Magnetism

What happens when a damaged apple is dropped into a bowl of water according to Newtonian physics?

• The apple floats

• The apple dissolves

• The water solidifies

• The water splashes up

What is a common household example of a non-Newtonian fluid?
