UCM and UG Physics

UCM- Uniform Circular Motion & UG - Universal Gravitation

QuestionAnswer
Centripetal forces are always ____ to the circle perpendicular
If the centripetal force disappears, an object will move... in a straight line at a constant speed
the force needed to cause rotation centripetal
Circular motion is accelerated because this is changing direction
Objects travelling in a circle are accelerating towards the center
Gravitational force depends on two masses
Gravitational force is inversely related to the square of the ___ between the two objects. distance
Graviational force and mass are ____ related directly
Gravity that occurs everywhere universal
Speed perpendicular to a circle tangential velocity
The speed of a UCM object moving in a circle is constant
This vector points in the same direction as the centripetal force centripetal acceleration
Always an attractive action reaction pair of forces gravitational force
If you increase the distance between two objects, the gravitational force between them will decrease
If you cut the distance between two objects in half, the gravitational force will quadruple
If you double one mass, the gravitational force it exerts on everything else will double
a change in this is acceleration velocity
three ways to accelerate speed up, slow down, change direction
the other name for gravitational force weight
Unit for weight and gravitational force Newton
The centripetal force when a car rounds a curve friction
The centripetal force when a waterskiier changes direction tension
tendency of an object to keep the same motion inertia
equation to calculate mass from weight Fw = mg
The time it takes to make one revolution (T) period
Universal gravitation constant, G 6.67 x 10^-11
acceleration due to gravity on earth, g -9.8 m/s^2

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.
