Newtons 1st Law of Motion - the Law of Inertia Explained!

This video explains Newton's First Law of Motion, also known as the law of inertia. It states that an object will remain at rest or in motion unless acted upon by an external force. The video provides examples like a soccer ball being kicked and a shopping cart rolling, illustrating how external forces change motion. Inertia is the tendency of objects to resist changes in motion, as shown in a car stopping suddenly. The video concludes by summarizing the law's key points.

What does Newton's First Law of Motion state about an object at rest?

• It will change direction spontaneously.

• It will remain at rest unless an external force acts on it.

• It will increase its speed over time.

• It will start moving on its own.

Which of the following is an example of an external force acting on a soccer ball?

• The ball sitting on the ground.

• The ball rolling on its own.

• A player kicking the ball.

• The ball changing color.

What is the term used to describe the tendency of an object to resist changes in its motion?

• Velocity

• Acceleration

• Inertia

• Momentum

In the example of a car stopping suddenly, what role does the seat belt play?

• It stops the car from moving.

• It changes the direction of the car.

• It accelerates the car.

• It prevents the passenger from moving forward.

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

• It will slow down gradually.

• It will change its direction.

• It will continue moving at the same speed and direction.

• It will stop immediately.
