UST Physics
Motion in one and two dimension, vectors
| Question | Answer |
|---|---|
| How many significant digits will be in a sum or difference? | The smallest number of decimal places of any term |
| How many significant digits will be in a product or quotient? | The lowest number of significant figures of the factors |
| SI System for length, time, and mass | meter (m), second (s), kilogram (kg) |
| CGS System for length, time, and mass | centimeter (cm), second (s), gram (g) |
| British System for length, time, and mass | feet (ft), second (s), pounds (lbs) |
| Distance | Distance traveled along actual path (scalar value) |
| Scalar | Having no positive(+) or negative (-) value necessary |
| Displacement | Object's final position in respect to initial position (vector) |
| Displacement Equation | DX = Xf - Xi |
| Average Velocity | V[average] = DX/Dt = (Xf-Xi) / (tf - ti) (measured in m/s) |
| Speed | V s = d/Dt (measured in m/s) |
| sin0 | y/r |
| cos0 | x/r |
| tan0 | y/x |
| Motion | Non-constant velocity needs to be averaged into slope of a straight line joining initial and final points |
| Instantaneous Velocity | average velocity in limit as the interval becomes infintesimaly short. |
| Acceleration | (Vf - Vi)/(Dt) |
