• Acceleration the rate with which velocity
  changes over time.
• If velocity does not change, there is no
  acceleration

4
Changing Acceleration

• Speeding up
• Slowing down
• Changing directions at a constant speed
• Changing directions while slowing down or
  speeding up

Investigation Acceleration

• MOVEMENT OF STRING
• ANSWER WHAT DO YOU THINK QUESTIONS

While speeding up While slowing down While walking steadily

10
Acceleration can be calculated from velocity and
time

• The change in velocity can be found by comparing
  the initial velocity and the final velocity of
  the moving object.

11
Formula for acceleration
12
Units for acceleration

• Units for a m/s2

13
Calculating Acceleration

• WRITE OUT Sample Problem

14
MATH PRACTICE PROBLEMS
15
Velocity-Time Graphs

• Velocity- time graphs are used to understand
  acceleration
• Draw Velocity-Time graph on page 30 (textbook)

16

• On the left side of notebook demonstrate your
  understanding of Section 1.3
• Thinking map, rap, comic strip, foldable
• Write your summary
