Vel/Acc
Velocity and Acceleration emphasizing graphing
| Question | Answer |
|---|---|
| Rate of change in position (no direction) | Speed |
| Rate of change in position (with direction) | Velocity |
| Rate of change in velocity | Acceleration |
| m/s | Velocity |
| Sum of all forces on an object | Net Force |
| m/s/s | Acceleration |
| Newtons | Force |
| meters | Distance/Displacement |
| Used to represent velocity | Distance-Time Graph |
| Used to represent acceleration | Velocity-Time Graph |
| Represented by a horizontal line on a distance-time graph | Not moving |
| Represented by a horizontal line on a velocity-time graph | Moving at a constant speed |
| Represented by a straight line going up and to the right on a distance-time graph | Moving at a constant speed |
| Represented by a straight line going up and to the right on a velocity-time graph | Speeding up at a constant rate |
| Represented by a curve going to the right and up on a distance-time graph | Speeding up at a constant rate |
| This word describes an object's resistance to change its motion | inertia |
| Inertia is closely connected to this property of matter | mass |
| The force of gravity pulling on an object | weight |
| The amount of matter in an object | mass |
| The amount of space an object occupies (takes up) | volume |
| Joules | energy |
| Watts | Power |
| Required to change the velocity of an object | Net Force |
| Law of Physics that describes inertia | Newton's First Law |
| Ratio of force to mass | acceleration |
| Can be calculated by squaring velocity and multiplying by mass | kinetic energy |
| Ratio of change in velocity to time | acceleration |
| Ratio of distance to time | velocity/speed |
| Ratio of mass to volume | density |
| Can be increased to increase inertia | mass |
| 3 ways to change velocity | speed up, slow down, change direction |
| Force that goes in the opposite direction of motion when matter touches | friction |
