Answer:

Many YEARS ago, Sir Isaac Newton came up with some most excellent descriptions about motion. His First Law of Motion is as follows: “An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force.” Quite a mouthful. What that means is that something that is sitting there will continue to sit there unless moved. And something moving will keep moving unless something stops it.

Still a mouthful. Just think about this: When you are at a stoplight in your car and you start moving quickly, you feel pushed back into your chair. The opposite is true if you come to a sudden stop, and you move keep moving forward, with only your SEATBELT preventing you from crashing forward.

Here are a couple of experiments that demonstrate this very cool law of motion; in a word called “inertia.”

Ball Bounce Experiment

Materials for the Ball Bounce Experiment:

A basketball or soccer ball, or similar bouncy ball

a smaller bouncy ball (like a tennis ball or a racquet ball).

Have an assortment of other balls handy for further experimenting.

Procedure:

Do this experiment outside

First bounce the basketball and tennis ball side by side to COMPARE their bounces. Start them off AROUND chest height

Make a hypothesis (a guess) about what will happen when you stack the SMALL ball on top of the bigger one and then drop it

Try it! It may take a couple tries to line them up just right but the results are pretty awesome
