Gravitation

QuestionAnswer
Definition of gravity assist When you use a nearby star / planets orbit to slingshot your craft into a flyby motion and gain momentum so it can travel further than the engine allows.
What formula is used for horizontal calculations d=vt
Name 1 formula used for vertical calculations v=u+at
What is the formula for gravitation? F=Gm1m2/r^2
What is 1 application of gravitational force? Gravity assist / slingshotting
What is a projectile? Any object which once projected, continues its motion by its own inertia and is only influenced by the downward force of gravity
What are the two components of a projectile? Vertical Horizontal
Definition of terminal velocity When an object is falling for long enough the magnitude of air resistance increases to match the objects weight. The result is balanced forces making the objects fall a now constant velocity.
What forces act on a horizontal projectile No forces act on this projectile producing a constant speed
What forces act on a vertical projectile A constant gravitational force producing constant acceleration
Formula for the vertical component V=Vvsinθ
Formula for the horizontal component V=Vhcosθ

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.
