Describe the velocity at E.

The velocity is small and positive. It was large and positive, but it has decreased until it is amost zero.

Describe the velocity of the object at E.

At E, the object has stopped, so it has zero velocity.

The word slope means ______________

Steepness

Describe the slope at point D

Small positive slope

As you go along the curve from A to E, the slope

Decreases

It goes from large negative to zero.

As you go from A to D, the slope

Increases.

It goes from a slope of zero to a large negative slope.

Describe the overall motion of this object.

Starts at rest in a negative position. It speeds up in the positive direction and passes the reference point.

Describe the velocity at E

Velocity at E is zero.

(the slope of a position/time graph **IS** the velocity)

Compare slopes at A and B

Both slopes are large and negative. A has a higher slope.

Describe the Slope

Contant zero slope

Describe the slope at point D

Small positive slope

Describe Slope at C

Slope at C is medium and negative

Describe position and velocity at point A

The object is at the reference point and has not yet started to move.

Describe the Slope

This is a medium constant negative slope.

Describe the slope or steepness at A.

Zero

Velocity at A

Zero

(remember, the slope of a position/time graph **IS** the velocity)

The slope at D is....

Large and Negative

Describe how the slope changes on this graph

The graph starts with a small positive slope. The slope increases until point "c" Then the slope begins to decrease.

The slope is positive at all times in this graph.

The slope at C is...

The slope at C is medium and positive

Describe how the slope changes

Negative Slope

Decreasing Slope

(We say the slope is "decreasing" when the "hill" is getting less steep.)

Describe the position at A

High positive position

Describe the velocity at A

High Positive Velocity

(Remember, the slope of a position time graph **IS** the velocity.)

Slope at E is....

Zero

Describe the Slope of the Purple Line

Medium Positive Constant Slope

Compare slopes at C and D.

Slopes at C and D are both large and negative. The slope at D is larger.

Velocity at C

Negative velocity

Describe the velocity of the object at A.

The velocity of the object at point A is zero.

How would you describe the slope (steepness) at point A?

High Positive Slope

Describe the slope or steepness at B

Small negative slope

Describe the Slope

The slope is medium, positive, and constant.
