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.
200
What is a simple machine?
Any of the basic mechanical devices for applying a 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?
An airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.
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 they are combined together.
300
What is a solid?
it has a certain size and shape.
300
What are sound waves?
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
400

What is the definition of force?

a push or pull upon an object

Why are simple machines helpful today?
Simple Machines are easy to access, and use(for our jobs, and it is a tool; which we can rely on for in our everyday lives.
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
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.

500
What is a screw?
a short, slender, sharp-pointed metal pin with a raised helical thread 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
What of the following are examples of a mixture? a.milk b.cheese c.wheat thins d.carbonated soda
The answer is a. and d. because they both include substances made up of other substances.
500
What is Matter?
is anything made up of atoms and molecules.

What are compressional waves, also refered to as?
"LONGITUDINAL WAVES"
