What is Newtons First law of motion?!
. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

What is a lever?
A rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.
100
What is an element?
an element is, a pure substance that CAN NOT BE BROKEN DOWN; into simpler substances.
100
What is an example, of a liquid? a.water based solutions b. iodine c. wheat crackers d. salt
The correct answer is a. and b. because they both are able to flow throughout the actual substance, and they both take up the shape; of the container.

What is the spectrum?
is a condition that is not limited to a specific set of values but can vary infinitely within a continuum.
200
What is Newtons Second Law of Motion?
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

What is a simple machine?

Any of the basic mechanical devices for multiplying an inputted force.

200
What is a compound? (HINT):examples of a compound are water and/or carbon dioxide
a compound is made up of two or more types of elements; that are "CHEMICALLY" combined.
200

What is a gas?

A fluid substance which expands freely to fill any space available, irrespective of its quantity. Particles are highly spaced out and very energetic.

200
What are light waves?
refers to electromagnetic radiation of any wavelength, whether visible or not OR electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye.
300
What is Newtons Third Law of Motion?!
For every action there is an equal and opposite reaction.
300
What is an inclined plane?
A plane inclined at an angle to the horizontal; or a sloping ramp up which heavy loads can be raised by ropes or chains
300

What is a mixture?

a mixture is a substance made by mixing other substances, and is able to be separated by physical means

300

What is a solid?

It has a certain size and shape. Its particles are tightly packed together and have relatively little movement. 

300

What are sound waves?

A longitudinal wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.

400

What is the definition of, force?

is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.

What is a simple machine in this room?

Answers will vary.

400
How are elements, compounds, and mixtures related to one another?
They all are made up compounds. They all require mass; which takes up space. They all are made up of elements.
400

States of Matter, are also referred to as?

The different phases of matter, solid, liquid, gas

400
What are compressional waves?
a shock wave that compresses the medium through which it is transmitted.
500
What is Mass?
the amount of matter, that there is in something.

What is a screw?

a short, slender, sharp-pointed metal pin with a raised helical inclined plane running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.

500

Which of the following are examples of a mixture? a.milk b.cheese c.trail mix d.carbonated soda

The answer is a. c. and d. because they both include substances made up of other substances.

What is Matter?

Matter is anything that has mass and takes up space.
