Physics Quiz #3: Study Guide
| Term | Definition, description, and/or examples |
|---|---|
| Mass | The amount of matter in an object; will not change based on gravity |
| Weight | A measure of force of gravity on an object; will change based on gravity |
| Frictional force | The force that resists movement across a surface |
| Dynamic / kinetic friction | Force of Friction between surfaces in motion; result of surfaces moving over one another. |
| Static friction | Force of friction between surfaces NOT in motion; result of surfaces adhering to each other; strongest form of friction |
| Sliding friction | Form of Kinetic/dynamic friction |
| Rolling friction | Form of Kinetic/dynamic friction; weakest type of friction |
| Inertia | The tendancy to remain unchanged (Newton’s 1st Law) |
| Acceleration | The increase (+) or decrease (-) in an object’s motion |
| Velocity | The direction and a rate at which an object is moving |
| Observe the image below; this illustration shows the girl pushing on a heavy boulder, but the boulder is not moving. Explain why the boulder does not move. While there may be a variety of reasons for this, explain how friction is affecting the motion of the boulder. |

 **** | Why is the person not able to move the objects? Include ideas about balanced/unbalanced forces in addition to static friction. |
|---|---|
| The person is unable to exert a force strong enough to overcome static friction, thus, the object remains stationary (Balanced forces) |
 **** | Why is the person able to move the object? |
|---|---|
| The person is able to exert a force strong enough to overcome static friction, thus, the object moves (Unbalanced forces). |
| DIRECTIONS: Calculate the mass and force (weight) for each of the following problems. If necessary, use the information below. |
|---|
| How do you calculate an object’s mass (g) to Newtons (N)?Divide the mass by 100How do you calculate an object’s force (N) to mass (g)?Multiply the force by 100 |
| What are Newton’s Laws and how do they exhibit principles from physics? |
|---|
| Law |
| Definition (simplify to terms you understand) |
| Application / connection to what we have done in physics (labs, activities, simulations, etc.) |
| DIRECTIONS: Calculate either the force, mass, or acceleration for each of the following problems. If necessary, use the information below. |
