Learn how to determine the number of times a particle changes direction table

The video tutorial explores the movement of a particle over various time intervals, focusing on whether the particle is increasing or decreasing. It identifies two main changes in direction and emphasizes the importance of specifying intervals when discussing these changes. The tutorial aims to clarify how to articulate changes in particle direction accurately.

During which time interval does the particle initially decrease?

• 0 to 5

• 5 to 10

• 10 to 15

• 15 to 20

What happens to the particle from 1 to 1.5?

• It increases

• It remains constant

• It decreases

• It stops

How many times does the particle change direction?

• One time

• Four times

• Two times

• Three times

In which interval does the particle change from decreasing to increasing?

• 0.5 to 1.5

• 3.5 to 4.5

• 1.5 to 2.5

• 2.5 to 3.5

What is the interval where the particle changes from increasing to decreasing?

• 3.7 to 4.7

• 1.5 to 2.7

• 2.7 to 3.7

• 0.5 to 1.5
