| A solid object with a single force placed on it in a single direction will accelerate in what kind of line? | Straight |
| A solid object that has two forces on it in different (but not opposite) directions will move in what shape? | Curved |
| Objects with many forces on them in many differnt directions move in what type of pattern? | Complex patterns |
| You can get what type of motion using inertia of a moving object and applying a force toward a center point (think orbit) | Circular |
| When forced is placed on fluid, what results? | Waves |
| What does "work" mean in physics? | A force applied over a distance. We calculate the amount of work that is done by multiplying the force by the distance over which the force is applied |
