Physical Sci

QuestionAnswer
the resistance of 2 objects rubbing against each other friction
smooth surface: less friction; will roll farther
rough surface: more friction; will not roll far
an invisible force that pulls objects gravity
objects touching. example: friction, springs contact force
objects not touching. example: gravity, magnet non-contact force
not moving/zero Newtons balanced force
is moving unbalanced
energy in motion kinetic energy
stored energy/not moving potential energy
keeps properties, is easily separated mixture
properties do change, harder to separate, dissolves solution
rate of dissolvement: 1.stir, 2. crush, 3. use hot water to dissolve something more quickly
a substances ability to dissolve solubility
substance that DOES dissolve. example: sugar, salt solute
dissolves other substances. example: water solvent
if something needs to be more concentrated... add solute
if something needs to be less concentrated.. add solvent
when a new substance is created chemical change
a change in shape, size or state of matter physical change
changes occurring in a chemical change: odor, color change, bubbles, energy released/absorbed
examples of chemical change rust, smell, grill, cook, burn, mold
examples of physical change cut, tear, bend, melt, evaporation, boiling
properties of matter solid, liquid, gas
an objects ability to sink or float density
magnetism: iron, cobalt, steel, nickel "I Can See Nick"
Hardness: 1= __________, 10 = __________ 1 = Softest, 10 = hardest, "Moh's Hardness Scale"
stored energy when materials stretch or compress(rubberband) elastic
energy stored in a substance due to chemical bonds(a match) chemical
energy stored when an object is in an elevated position gravitational
increasing the speed acceleration
standard unit of force newton
sum of all forces acting on an object net force
1st law of motion aka law of inertia an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force
2nd law of motion the greater the mass of an object, the greater the amount of force is needed to move an object
3rd law of motion for every action, there is an equal and opposite reaction

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:

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.
