| Question | Answer |
|---|---|
| What is the speed and direction something seems to be going from a certain point of view | relative velocity |
| What is the resistance of an object to a change in motion | inertia |
| what does Buoyancy mean | An upward force exerted by any fluid |
| what is Balanced Force | Same sized forces acting in opposite directions. Results in no motion |
| what is Unbalanced Force | When one force is greater in one direction. Results in motion of an object |
| what does Inertia mean | An objects resistance to a change of motion |
| Distance divided by time | speed |
| The measure of the space between objects | Distance |
| what is Motion | Change of position of an object |
| Object used to determine motion | reference point |
| Speed with direction | velocity |
| what is displacement | The measure of the change of position from its original position |
| What is the size or extent of a force | magnitude |
| If a skydiver jumps from an airplane and the upward force of air resistance becomes equal to the downward pull of gravity, when these two forces become equal in magnitude, what will happen to the skydiver | he will fall at a constant speed |
| what is vector | An arrow used to show the direction of the force |
| what is force | any push or pull on an object |
| what is Force of friction slowing an object down in a fluid | drag |
| what is a force when a rock is falling down a hill | gravity |
| what force is pulling down the tree | gravity |
| when your in the car and you step on the breaks what force is that | friction |
