  1. DVTA Jeff Ikner Physics

  2. What is the displacement of an object measured over an interval of time? • average velocity • What is the rate of change in velocity? • acceleration

  3. A change in position in a particular direction. • displacement • A plot of the acceleration of an object as a function of time. • Acceleration Time Graph • Acceleration which does not change during an interval of time. • constant acceleration

  4. Velocity which does not change during an interval of time. • constant velocity • The length moved between two points. • distance • The velocity at which an object starts at the beginning of a time interval. • initial velocity

  5. The value of a quantity at a particular instant of time, such as position, velocity, or acceleration. • Instantaneous • The study of how motion occurs. • Kinematics • The zero location in a coordinate system. • reference point

  6. The ratio of distance to time. • speed • What two centuries marked the beginning of our modern understanding of motion? • 16th and 17th • What two scientists are given credit for the study of motion? • Galileo and Newton

  7. What two parts is mechanics divided? • Kinematics and Dynamics • Objects that move without rotating exhibit ___________ motion. • translational • An ___________ particle is a mathematical point with no spatial dimensions. • idealized

  8. The description of how objects move. • Kinematics • The study of force and why objects move as they do. • Dynamics • This is a measure of how far an object is from its starting point. • displacement

  9. The sum of the magnitudes of the lengths that an object has traveled. • distance • A quantity that has both magnitude and direction. • A vector • A quantity with magnitude only. • A scalar

  10. Average velocity is defined in terms of ____________, not distance. • displacement • Average speed and average velocity have the same magnitude when the motion is all in _____ ________. • one direction • When an object is slowing down we say that it is __________ • decelerating

  11. The five kinematic equations are only useful if acceleration is __________. • uniform • nano • 10-9 • Tera • 1012 • milli • 10-3

  12. deka • 101 • kilo • 103 • pico • 10-12 • Mega • 106

  13. Giga • 109 • micro • 10-6 • deci • 10-1 • centi • 10-2

  14. hecto • 102 • Why is 100 = 1? • We know that 1000/1000 = 1. • 1000 = 103 • 103 / 103 = 103-3 = 100 • Therefore, 100 must be equal to 1.

  15. What is the slope of a velocity time graph? • acceleration • What is the slope of a distance time graph? • velocity • What is the area beneath a velocity time graph? • distance

  16. What is the area beneath an acceleration time graph? • velocity
