1. distance-time graph

1.1. Line graph used to show the speed of a moving object

2. Velocity-time graph

2.1. a graph that can be used to plot the velocity of an object versus time and to determine the sign of an object's acceleration

3. Mass

3.1. The total amount of matter in an object.

4. Acceleration

4.1. Acceleration is the rate of change of the velocity in time. Formula = a=vf-vi/t

5. Time Interval

5.1. Time between to events

6. Macroscopic Object: objects large enough to be visible almost practically with the naked eye, without magnifying optical instruments.

7. Relation between force and acceleration: Directly proportional

7.1. Acceleration and mass: Inversely proportional

8. Net force: The overall force on an object when all the individual forces acting on it are added together

9. Velocity

9.1. The speed of an object in a particular direction. Formula = distance/time

10. Quantities

10.1. Scalar: a physical measurement that can be described by magnitude only and has no direction

10.2. Vector: A physical measurement that contains directional information

11. Displacement:

11.1. Distance and direction of an object's change in position from the starting point.

12. Instantaneous Velocity: the velocity of an object at some instant or at a specific point in the object's path

13. Force: A push or pull exerted on an object

13.1. Force = mass X acceleration (Units = Newtons)
