Isaac Newton 3 Laws of Motion /Newton's Laws

The video introduces Isaac Newton and his groundbreaking contributions to physics, focusing on his three laws of motion. The first law, inertia, describes how objects remain at rest or in uniform motion unless acted upon by an external force. The second law explains the relationship between an object's mass, acceleration, and applied force. The third law states that for every action, there is an equal and opposite reaction, demonstrated through Newton's Cradle. Each law is explained with examples to aid understanding.

What was one of Isaac Newton's major contributions to physics?

• The theory of relativity

• The laws of thermodynamics

• The three laws of motion

• The discovery of electricity

According to Newton's First Law, what happens to an object at rest if no external force acts on it?

• It will accelerate

• It will change direction

• It will remain at rest

• It will start moving

Which example best illustrates Newton's First Law of Motion?

• A car accelerating on a highway

• A ball rolling down a hill

• A book lying on a table

• A rocket launching into space

What does Newton's Second Law of Motion describe?

• The relationship between force, mass, and acceleration

• The concept of inertia

• The conservation of energy

• The behavior of gases

Newton's Third Law of Motion states that for every action, there is:

• A greater reaction

• An equal and opposite reaction

• A similar action

• No reaction
