Balanced Force A balanced force is when two equal forces are applied on an object pushing both ways. Also they are equal forces acting on an object in opposite directions
Unbalanced Force Unbalanced forces: Forces that produce a non-zero net force, which changes an object's motion.
Groups number of valence electrons
Physical Change are changes affecting the form of a chemical substance, but do not change the chemical composition of that substance.
Atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons
Chemical Equations consists of the chemical formulas of the reactants (the starting substances) and the chemical formula of the products (substances formed in the chemical reaction).
Speed The rate or a measure of the rate in motin
Newton's first law If an object experiences no net force, then its velocity is constant: the object is either at rest (if its velocity is zero), or it moves in a straight line with constant speed (if its velocity is nonzero).
Rows period
Acceleration is the rate at which the velocity of a body changes with time
Density p=m/v
Flask laboratory glassware for holding larger volumes than simple test tubes
test tube also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom
goggles safety glasses are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes
triple beam balance measures grams
velocity rapidity of motion
force a push or pull
newton unit of force equal to the force needed to accelerate 1kg or 1m per sec.
direction the act or function of directing
thrust strong push that quickly moves an object

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
