1. Ch. 2 Graphing of Motion in One Dimension

2. Displacement-time Graph (  x vs.  t) Slope equals velocity. The "y" intercept equals the initial displacement.

3. – When two curves coincide, the two objects have the same displacement at that time. – Straight lines imply constant velocity.

4. Curved lines imply acceleration. An object undergoing constant acceleration traces a portion of a parabola.

5. – Average velocity is the slope of the straight line connecting the endpoints of a curve. – Instantaneous velocity is the slope of the line tangent to a curve at any point.

6. – Positive slope implies motion in the positive direction. – Negative slope implies motion in the negative direction.

7. -Zero slope implies a state of rest or no motion. -The area under a curve is meaningless, it tells us nothing.

8. Velocity-time graph (Vel. vs.  t) – Slope equals acceleration. – The "y" intercept equals the initial velocity.

9. – When two curves coincide, the two objects have the same velocity at that time. – Straight lines imply uniform acceleration.

10. – Curved lines imply non- uniform acceleration. – An object undergoing constant acceleration traces a straight line.

11. - Average acceleration is the slope of the straight line connecting the endpoints of a curve. - Instantaneous acceleration is the slope of the line tangent to a curve at any point.

12. -Positive slope implies an increase in velocity in the positive direction. - Negative slope implies an increase in velocity in the negative direction.

13. - Zero slope implies motion with constant velocity. - The area under the curve equals the change in displacement.

14. Acceleration-time graph (a vs.  t) – Slope is meaningless. – The "y" intercept equals the initial acceleration.

15. – When two curves coincide, the two objects have the same acceleration at that time. – An object undergoing constant acceleration traces a horizontal line.

16. – Zero slope implies motion with constant acceleration. – The area under the curve equals the change in velocity.
