When is the particle increasing decreasing from a velocity graph

The video tutorial explains how to analyze slopes on a graph, focusing on identifying positive and negative slopes over different intervals. It emphasizes the relationship between velocity and slope, particularly when the slope is increasing or decreasing. The tutorial also covers how to justify speed changes correctly, avoiding common mistakes. Key concepts include understanding when speed is increasing or decreasing based on slope behavior.

What is the slope of the graph from interval one to two?

• Undefined

• Zero

• Negative

• Positive

When is a graph considered to be increasing?

• When the slope is undefined

• When the slope is positive and increasing

• When the slope is negative

• When the slope is zero

What should not be confused with velocity when analyzing the graph?

• Distance

• Acceleration

• Speed

• Time

Why can't the derivative be taken at time interval 2?

• Because the slope is zero

• Because it's a sharp edge

• Because the slope is positive

• Because the slope is negative

What happens to the speed when V sub T is less than 0 and the slope is decreasing?

• The speed is decreasing

• The speed is undefined

• The speed is constant

• The speed is increasing

What is the condition for the speed to decrease when the velocity is positive?

• The slope is increasing

• The slope is undefined

• The slope is decreasing

• The slope is zero

In which interval is the speed decreasing when V sub T is less than 0 and the slope is increasing?

• From 3 to 21.5

• From 2 to 3

• From 1 to 2

• From 0 to 1
