| Question |
Answer |
| The state in which one object’s distance from another object is moving | Motion |
| A place or point used for comparison to determine if an object is in motion | Reference Point |
| A version of the metric system used by scientists all over the world | Internation System of Units (SI) |
| The SI unit for length | Meter |
| The distance that an object travels per unit of time | Speed |
| What is the formula (equation) used to find speed | S = D/T; Speed = Distance/Time |
| Tell a metric unit for speed | Km/hr, m/s |
| The overall rate of speed that an object moves, comparing the total distance traveled and the total time | Average Speed |
| The rate of speed that an object is moving at a particular instant or time | Instantaneous Speed |
| Speed in a given direction | Velocity |
| The steepness of a line on a line graph | Slope |
| How do you calculate the slope of a line? | Slope = Rise/Run |
| On a graph that shows Distance V/S Time, what does the slope of the line represent? | The Speed |
| On a graph that shows Distance V/S Time, what does a steep slope mean? | The speed is fast |
| On a graph that shows Distance V/S Time, what does a gradual slope mean? | The speed is slow |
| On a graph that shows Distance V/S Time, what does a horizontal line mean? | Slope = 0, so the object is not moving. |
| The rate at which the velocity of an object changes | Acceleration |
| What are the three things that can cause acceleration? | Increase in speed, Decrease in speed, or Change in direction |
| What is the formula (equation) used to find acceleration? | A = (Final Speed - Initial Speed)/Time |
| What is the metric unit for acceleration? | (m/s)/s or m/s2 |
| What does it mean if an object has a positive acceleration? | It is speeding up |
| What does it mean if an object has a negative acceleration? | It is slowing down |
| What does it mean if an object has no acceleration (A = 0)? | It is moving at a constant speed |
