11.3 ICP Acceleratio
11.3 Icp
| Question | Answer |
|---|---|
| acceleration | rate at which velocity changes over time, can be an increase in speed or decrease in speed |
| free fall | motion of an object falling under the sole influence of gravity without other forces acting on it, constant rate of 9.8 m/s |
| constant acceleration | acceleration that remains the same over a period of time. velocity changes at a steady rate |
| linear graph | where the relationship between two variables is represented by a straight line, constant rate of change between the variables |
| nonlinear graph | where the relationship between two variables is represented by curve, changing rate of change between the variables |
| change in velocity | final velocity minus initial velocity another name for acceleration, change in speed, change in direction, or both |
| slope | rate of change between two physical quantities, divide the y axis unit by the x axis unit |
| gradient | vector that measures how fast in what direction a scalar field changes per unit distant, rate of change or slope |
| scalar | physical quantity that has magnitude only and no direction, speed and time examples |
| quantitative | is an amount or quantity or magnitude to relate to numbers |
