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.

What is Newtons Second Law of Motion?

the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

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 pressure, 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.
400
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

What is Matter?

anything that has both mass and takes up space

400

Which type of electromagnetic radiation has the highest energy and shortest wavelength?

Gamma rays

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. Salt water
b. Oxygen gas
c. Salad
d. Table sugar

The answer is a. and c. because they both include substances made up of other substances but are not chemically combined.

What is Plamsa?

It's an ionized gas where electrons are stripped from atoms, creating a mixture of charged particles
