This concept of a balanced versus and unbalanced force will be discussed in more detail later in Lesson 1.

Suppose that you filled a baking dish to the rim with water and walked around an oval track making an attempt to complete a lap in the least amount of time.

Isaac Newton (a 17th century scientist) put forth a variety of laws that explain why objects move (or don't move) as they do.


The water resisted this change in its own state of motion.

The water tended to "keep on doing what it was doing." The container was moved from rest to a high speed at the starting line; the water remained at rest and spilled onto the table.

If in motion with an eastward velocity of 5 m/s, they will continue in this same state of motion (5 m/s, East).

If in motion with a leftward velocity of 2 m/s, they will continue in this same state of motion (2 m/s, left).

Perhaps you could speculate what would occur when no seat belt is used. Using duct tape, attach two tennis balls to opposite ends of the coat hanger as shown in the diagram at the right.

There are many more applications of Newton's first law of motion. Perhaps you could think about the law of inertia and provide explanations for each application. Bend the hanger so that there is a flat part that balances on the head of a person. Spread over 38,863 km (15,005 sq mi), it is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west.With 33,387,677 inhabitants as per the 2011 Census, Kerala is the thirteenth-largest Indian state by population.On the other hand, when braking from a state of motion the coffee continues forward , ultimately hitting the windshield or the dash. Have you ever experienced inertia (resisting changes in your state of motion) in an automobile while it is braking to a stop?The force of the road on the locked wheels provides the unbalanced force to change the car's state of motion, yet there is no unbalanced force to change your own state of motion.The water would have a tendency to spill from the container during specific locations on the track.
