  1. IPS Terminal Velocity Expedition 2: A Universe of Motion

  2. Speed is the distance traveled over a given period of time. Instantaneous speed is the speed of an object at an exact moment in time.

  3. Speed is the distance traveled over a given period of time. Instantaneousspeed is the speed of an object at an exact moment in time.

  4. The slopeofthe line on a graph of distance vs time indicates how fast the object is going

  5. Stage 1: On the Move • Speed is an example of a scalarquantity. It only shows "how fast" the car is traveling, and does not show in which direction the car is traveling.

  6. Velocity- A vectorquantity

  7. Stage 1: On the Move • Velocityis a vector quantity which represents both the speed and the direction in which an object is moving.

  8. Acceleration describes these changes in speed and direction.

  9. When the velocity of a moving object decreases, it is said to decelerate, or undergo negative acceleration.

  10. Acceleration describes changes in direction as well as those in speed. Starting acceleration is zero. The time during which it moved is plotted horizontally on the x-axis. Its velocity is plotted vertically on the y-axis. The slope of the line illustrates whether the object is speeding up or slowing down.

  11. So far we have explored linear motion, or motion in a line or in one dimension.

  12. _________________ is an object’s mass multiplied by its velocity.

  13. If the velocities of two objects are the same, the object with more mass will have more momentum.

  14. If the masses of two objects are the same, the object with a highervelocity will have more momentum.

  15. ___________________ is an object’s resistance to change in its state of motion.

  16. The law of conservation of momentum tells us that momentum is neither lost nor gained, but rather is transferred between objects.
