Question

Write down a hypothesis and observational experiment to test one of Newton’s laws of motion. Explain your reasoning please!

Answer #1

Penny on a Card Experiment to test the law of inertia. An object at rest remains at rest unless and external force acts on it.

**Materials for the Penny on the Card
Experiment:**

- a small plastic cup,
- a playing card
- a coin.

**Procedure**:

- Put a playing card on top of the plastic cup
- Put a coin on top of the card
- With a sharp flick, hit the card out from under the coin! Or pull it really quickly toward you.
- The coin will drop into the cup.

**Explanation:**

The coin has inertia, meaning it really wants to stay in one place. If you move the card slowly, it isn’t fast enough to overcome that force. If you flick it quickly, the coin stays in one place and then drops into the cup. An object at rest will remain at rest.

2. Write down Newton’s 3 Laws of Motion. What assumptions must
be made for Newton’s Laws to be valid?
3. What quantities have we learned about that are conserved?
What must be true for each to be conserved?

1) What are the two conditions where Newton’s Laws of Motion
break down?
2) What are the two postulates of Special Relativity?
3) What is an inertial frame of reference?

Write Newton’s 3 laws IN YOUR OWN WORDS in detail (paragraph
form)

2- Use Galileo’s Thought Experiment to explain the second part
of Newton’s First Law of Motion. Please include an illustration to
give a clearer explanation

A student fly has just learned Newton’s Third Law of Motion. He
decided to do a daredevil experiment by colliding head-on with a
speeding car. The fly reasons out, “By Newton’s Third Law, the
force I apply on the windshield of the car is only equal but
opposite to the force of the windshield applied to me; therefore, I
will not be harmed”. Of course, the fly was crushed to death! Use
Newton’s Third Law to explain what was wrong...

You are asked to do a real experiment based on LAWS OF ENERGY
AND MOTION. Create a powerpoint about what you did in the
experiment, or write a paper about your experiment. This is not a
research paper, this is actually doing an experiment.
Include images of your experiment if you are not submitting a
video of the actual experiment. Additional bonus will be available
for production quality, more complex experiment, or humorous
submissions.
Here are past examples of exemplar...

1- When conducting a hypothesis test, one may
select to use α = 0.05. Explain what this means,
2- Provide an example to support your answer.
Make sure you indicate the null hypothesis and the alternative
hypothesis for your example.
Ho:
Ha:

come up with a topic and write out the null hypothesis and
alternative hypothesis. Would your test be two-sided or
one-sided?
