WHAT IS NEWTON'S 1ST LAW? |
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is often called "the law of inertia". |
|
|
WHAT IS NEWTON'S 2ND LAW? |
Acceleration is produced when a force acts on a mass. The greater the mass the greater the amount of force needed to accelerate the object. |
|
|
WHAT IS NEWTON'S 3RD LAW? |
For every action there is an equal and opposite reaction. |
|
|
WHAT ARE ATOMS? |
the smallest component of an element having the chemical properties of the element, consisting of a nucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleus by electrical attraction; the number of protons determines the identity of the element. |
|
|
WHAT ARE PROTONS? |
a positively charged elementary particle that is a fundamental constituent of all atomic nuclei. |
|
|
WHAT ARE NEUTRONS? |

|
|
WHAT ARE ELECTRONS? |
An elementary particle that is a fundamental constituent of matter. It existing independently or as the component outside the nucleus of an atom. |
|
|

|
WHAT IS HYDROGEN? |
A colorless, odorless, flammable gas that combines chemically with oxygen to form water; the lightest of the known elements. |
|
|
WHAT IS A SOLID? |
having relative firmness, coherence of particles, or persistence of form. |
|
|
WHAT IS A LIQUID? |
a substance possessing perfect molecular mobility and the property of indefinite expansion; not a gas or solid |
|
|
WHAT IS A GAS? |
a substance possessing perfect molecular mobility and the property of indefinite expansion. |
|
|
WHAT IS THERMAL ENERGY? |
is the energy that is generated and measured by heat |
|
|
WHAT IS HEAT? |
is generated from the movement of particles |
|
|
WHAT IS PARTICLE MOTION? |
a change in position of particles |
|
|
WHAT IS TEMPERATURE? |
a measure of the warmth or coldness of an object or substance with reference to some standard |
|
|
WHAT IS KINETIC ENERGY? |
moving energy |
|
|
WHAT ARE PHASES OF MATTER? |
the states in which matter can exist. |
|
|
WHAT ARE PHYSICAL PROPERTIES? |
do not change the chemical nature of matter. If I measure these properties the substance will not change. Example: color, smell, freezing point |
|
|
WHAT ARE CHEMICAL PROPERTIES? |
do change the chemical nature of matter. If I measure these properties the substance will change. Example: the substances will regroup differently |
|
|
WHAT ARE PHASES OF MATTER? |
the states in which matter can exist. |
|
|
WHAT IS A CHEMICAL REACTION? |
rearrangement of molecules of a substance |
|
|
WHAT IS SOLUABILITY? |
substances ability to dissolve in water |
|
|
WHAT IS A LINEAR SYSTEM? |
Extractions --> production --> distribution-->trash --> toxic |
|
|
WHAT IS EXTRACTION? |
A way to separate a desired substance when it is mixed with others. |
|
|
WHAT IS PRODUCTION? |
combining various material inputs and immaterial inputs in order to make something for consumption |
|
|
WHAT IS DISTRIBUTION? |
the process of moving a product from its manufacturing source to its customer |
|
|
WHAT IS TRASH? |
anything worthless, useless, or discarded |
|
|
WHAT IS TOXIC? |
acting as or having the effect of a poison |
|
|
WHAT IS DIOXIN? |
the most dangerous toxin |
|
|
WHAT IS NATURAL RESOURCE? |
materials found in the environment that is provided by nature and not made by man |
|
|
WHAT IS SYNTHETIC MATERIALS? |
made from natural resource: nylon, acrylic, polyester, spandex, carbon fiber. |
|
|

it is capable of being renewed |
|
|

it can be used again |
|
|
WHAT IS SUSTAINABLE: |
it is able to be maintained at a certain rate level (not harming) |
|
|
WHAT IS FORCE? |
a push or pull that acts upon an object as a result of its interaction with another object |
|
|
WHAT IS NORMAL? |
when an object is resting and is pushing back at the same force |
|
|
WHAT IS APPLIED? |
when someone is applying more force to the object. The force that the object applies is the greatest. |
|
|
WHAT IS GRAVITY? |
something that is in our atmosphere. It is a force. |
|
|
WHAT IS FRICTION? |
a force that is applied when objects rub against on another. It normally slows an object down |
|
|
WHAT IS AIR RESISTANCE? |
something that travels through the air. Force of the atmosphere. (force being applied on an object being on at atmosphere) |
|
|
HOW DOES INERTIA AFFECT THE MOTION OF AN OBJECT? |
the object keeps moving. It will keep moving until it is stopped. |
|
|
WHAT IS THE RELATIONSHIP BETWEEN INERTIA AND MASS? |
if something is moving but has more mass, it will be hard to stop. If something is not moving and has more mass, it needs to have force to move |
|
|
WHAT IS SPEED? |
how fast or slow something moves in a given amount of time Speed = distance/time |
|
|
WHAT IS MASS? |
how much matter there is in something. |
|
|

speed and direction velocity = distance/time + direction (north, south, east and west) |
|
|
WHAT IS ACCELERATION? |
the measurement in the change of velocity of an object |
|
|
WHAT IS MOMENTUM? |
the property of moving objects that makes them hard to stop Momentum = (velocity)(mass) |
|
|
WHAT ARE FORCES? |
gravity applied normal friction air resistance |
|
|
WHAT IS NORMAL? |
conforming to a standard; usual, typical or expected |
|
|
WHAT IS INERTIA? |
a tendency of an object to resist change in its motion |
|
|
WHAT TERMS ARE ASSOCIATED WITH NEWTON'S 1ST LAW? |
Speed Velocity Acceleration |
|
|
WHAT ARE EXAMPLES OF ACCELERATION? |
riding a carousel crossing a finish line falling freely spinning a basketball |
|
|
WHAT IS FEELING ACCELERATION? |
An example: when you ride in a car and it speeds up, you feel as though you are being pressed against the seat. When the car slows down, you feel like you are being pushed forward, especially if the change in speed is sudden. |
