| What is the acceleration of falling objects? | 9.8 m/s/s |
| How does air resistance affect the acceleration of falling objects? What is air resistance? | It slows down falling objects. It is fluid friction. |
| What is terminal velocity? | a constant velocity |
| When is an object in a free fall? | When gravity is pulling down on it and no other forces are acting on it. |
| What two motions make up an orbit? | Moving foward and a free fall. |
| What is inertia? | The tendency of objects to resist any change in motion. |
| What two things does acceleration depend on? | The mass and force applied. |
| What is the formula for Newton's second law? | a=f/m or f=mxa |
| What two things does momentum depend on? | mass and velocity. |
| What does Newton's first law state? | An object at rest stays at rest and an object at motion stays at motion unless acted upon by an unbalanced force. |
| What does Newton's second law state? | The acceleration of an object is dependent upon the force acting on the object and the mass of the object.n |
| What does Newton's third law state? | Every action has an equal and opposite reaction. |
| A force that makes any object pull toward another object is ________. | gravity |
