  1. Linear Kinematics

  2. Kinematics Study of motion of objects without regard to the causes of this motion.

  3. Linear Relationship between variables acted in the same plane.

  4. Reference Point Zero location in a coordinate system or reference frame

  5. Position Separation between object and a reference point.

  6. Instantaneous Position Position of object at a specific time

  7. Scalar Quantity that has only a magnitude or size. It is just a measurement.

  8. Magnitude Size or measurement

  9. Vector Quantity having both magnitude and direction.

  10. Distance The separation between two points. A scalar quantity.

  11. Displacement Change in position. A vector quantity.

  12. Speed Ratio of distance to time

  13. Velocity Ratio of change in position to time interval over which change takes place.

  14. Instantaneous Velocity The velocity of an object at a specific point in time.

  15. Initial Velocity Velocity of object at time: t=0 s or when recording starts.

  16. Final Velocity The velocity of the object at the point of time in question or when recording stops.

  17. Acceleration Change in velocity divided by time interval over which it occurred.

  18. Instantaneous Acceleration The measurement of the acceleration of an object at a specific point in time.

  19. Gravity The acceleration an object has towards the mass it is attracted.

  20. Formulas

  21. Position-time Graph Graph of object’s motion that shows how its position depends on time.

  22. Velocity-time Graph Plot of velocity of object as a function of time.

  23. moving with a constant, positive velocity is shown. A positive, constant velocity is represented by a line with constant slope (straight) and positive slope (upwards sloping).

  24. moving with a constant, negative velocity is shown. A negative, constant velocity is represented by a line with constant slope (straight)

  25. moving in the + dir'n and accelerating from a low velocity to a high velocity is shown. If the object is moving in the + dir'n, then the slope of a p-t graph would be +.

  26. If the object is changing velocity from small to large values, then the slope must change from small slope to large slope.

  27. moving in the + dir'n and accelerating from a high velocity to a low velocity is shown. If the object is moving in the + dir'n, then the slope of a p-t graph would be +.

  28. If the object is changing velocity from high to low values, then the slope must change from high slope to low slope.

  29. moving in the - dir'n and accelerating from a high velocity to a low velocity is shown. If the object is moving in the - dir'n, then the slope of a p-t graph would be -.

  30. If the object is changing velocity from high to low values, then the slope must change from high slope to low slope.

  31. moving in the - dir'n and accelerating from a low velocity to a high velocity is shown. If the object is moving in the - dir'n, then the slope of a p-t graph would be -.

  32. If the object is changing velocity from low to high values, then the slope must change from low slope to high slope.

  33. moving in the + dir'n with constant speed; first a slow constant speed and then a fast constant speed is shown. If an object is moving in the + dir'n, then the slope of the line on a p-t graph would be +.

  34. At first, the line has a small slope (corresponding to a small velocity) and then the line has a large slope (corresponding to a large velocity).

  35. moving in the + dir'n with constant speed; first a fast constant speed and then a slow constant speed is shown. If an object is moving in the + dir'n, then the slope of the line on a p-t graph would be +.

  36. At first, the line has a large slope (corresponding to a large velocity) and then the line has a small slope (corresponding to a small velocity).

  37. moving in the - dir'n with constant speed; first a slow constant speed and then a fast constant speed is shown. If an object is moving in the - dir'n, then the slope of the line on a p-t graph would be -.

  38. At first, the line has a small slope (corresponding to a small velocity) and then the line has a large slope (corresponding to a large velocity).

  39. moving in the - dir'n with constant speed; first a fast constant speed and then a slow constant speed is shown. If an object is moving in the - dir'n, then the slope of the line on a p-t graph would be -.

  40. At first, the line has a large slope (corresponding to a large velocity) and then the line has a small slope (corresponding to a small velocity).
