What is Newtons Third Law of Motion?!
For every action there is an equal and opposite reaction.
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.
What is an element?
an element is, a pure substance that CAN NOT BE BROKEN DOWN; into simpler substances.
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.
What is Newtons Third Law of Motion?!
For every action there is an equal and opposite reaction.
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
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.
What is a gas?
An air like fluid substance which expands freely to fill any space available, irrespective of its quantity
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
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
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.
What is a mixture?
a mixture is a substance made by mixing other substances; and they are combined together.
What is a solid?
it has a certain size and shape.
What are sound waves?
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
Want 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.
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.
What is Matter?
is anything made up of atoms and molecules
What are compressional waves?
a shock wave that compresses the medium through which it is transmitted.
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 applying a force.
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.
States of Matter, are also referred to as?
the different phases of matter
What are compressional waves, also refered to as?
LONGITUDINAL WAVES"
