Is a scientific law the same as a theory?
No
100
What is a theory often confused with once it is proven?
A law.
100
What is Newton's 1st law?
An object in motion will stay in motion, an object at rest will stay at rest, unless acted upon by an outside force.
100
What do the 'F' the 'M' and the 'A' stand for in Newton's second law?
F=force, M=mass, A=acceleration
100
What is Newton's 3rd law?
Every action has an equal or opposite reaction.
200
What is a scientific law?
A statement that cannot be disproved
200
What is a theory?
A well-supported and well-documented explanation for our observations.
200
What is the "outside force" that is present on earth, but not in space?
Gravity
200
What is the equation for the second law?
Force=Mass*Acceleration

If you blow up a balloon, untie the knot, and release it, in which direction will it go?
Away from you
300
How many laws did Isaac Newton create?
Three
300
What can a theory never become?
A theory never become a law

In the given scenario, what is the outside force?
The pencil bag

If the force of a car moving is 10 newtons and the mass of the car is 2 kilograms, what is the acceleration of the car?
5 units/sec/sec
300
Why don't action and reaction forces cancel each other out?
The forces are balanced and the object does not move either way.
400
Why is "E=mc²" a law?
It can not be broken no matter what.
400
Describe the cell theory and why it is a theory, not a law.
Cell theory- All living things are made of cells; All cells come from other cells; Cells are the basic building units of life. This is a theory because it hasn't been proven wrong and there's no way to prove it wrong. There is a mountain of evidence in favor of it.
400
In the given scenario, how is Newton's 1st law present?
The object will keep moving until the outside force(the pencil bag) stops it.

Force/Acceleration=...?
Mass

Define Newton's 3rd law in your own words.
Everything that happens in the universe will have an equal and opposite reaction.
500
Why are traffic laws not the same as scientific laws?
Traffic laws can be broken; scientific laws cannot.
500
If a theory is not perfectly accurate or scientifically useful, is it still considered a theory?
Yes.
500
Define Newton's 1st law in your own words.
An object will keep moving, or stay still unless something affects it.

If the force of the skateboard is 32 newtons and the acceleration is 12 meters/sec/sec, what is the mass of the skateboard?
2 and 2/3 or 2.667 kilograms

A firefly strikes the windshield of a moving bus. This is an obvious display of Newton's third law. The firefly hits the bus and the bus hits the firefly. Which force is greater-the bus, the firefly, or is it the same amount of force?
It is the same amount of force.
