# Centripetal Physics

### Centripetal force + gravitational law

TermDefinition
changing acceleration bc... changing direction
centripetal force is... the Fnet between Fn and Fg
centripetal force points towards... the center
central pointing acceleration caused by... central pointing Fnet
magnitude of acceleration in CONSTANT but... DIRECTION is changing
Fc= m x ac
Direction of velocity is changing constantly as... it moves around the circle
velocity is always... PERPENDICULAR to arc (TANGENTIAL to curve)
ac= V^2 (tan) / r
TANGENTIAL velocity V= displacement / time
CIRCLE V= 2 pi r (circumference) / T (period)
Universal Gravitation Law ALL mass is attracted to all other mass The strength of the gravitational force is DIRECTLY proportional to both MASSES and INVERSELY proportional to the DISTANCE between their centers
Newton's 3rd Law For every action, there is an equal and opposite reaction force
Newton's 2nd Law a= Fnet / mass a is DIRECTLY proportional to Fnet and INVERSELY proportional to mass Fnet is DIRECTLY proportional to mass
Newton's 1st Law An object w constant position or constant velocity will remain the same unless acted upon by a net external force
Equation of FG | FG |= G m1 x m2 / r^2
G= 6.67 x 10^-11 Nm^2 / kg^2 (universal gravitation constant)

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.
