| Question | Answer |
| 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 |
