2. At the end of the lesson student should be able to;
1. Define acceleration.
2. Calculate acceleration.
3. Relate acceleration from our daily lives.
Learning
Objectives:

3. Watch and listen
carefully!
Acceleration

4. The rate of change in velocity of an object.

5. How can we
say that an
object is
accelerating?

6. Change

ACCELERATI
ON

7. “ The object increases its acceleration. “
POSITIVE ACCELERATION
DECELERATION
“ The object decreases its acceleration. “

8. Do you think
Acceleration and
High Speed are the
same?

9. NO!
WHY?

10. Can we consider a car
travelling in a straight line
with constant speed as an
acceleration?

11. An ambulance travelling North
and then go to the East to go
at the hospital?

12. HOW TO
CALCULATE
ACCELERATION?

13. Change in velocity over time
ACCELERATI
ON

14. EXAMPLE # 1
A car accelerate from rest
to 24m/s in 6 s. What is the
average acceleration?

15. EXAMPLE # 2
A Baliuag transit bus is
travelling to north with a
velocity of 60m/s slows down
to a velocity of 40 m/s within
10s. What is the average
acceleration of the bus?

16. EXAMPLE # 3
A dog is lounging in the front
yard when it suddenly spots a
squirrel, it begins to run after
the squirrel and reaches a
final velocity of 3.45 m/s .
What is the time if the average
acceleration is 1.41m/s²?

17. - Acceleration is the rate of change in
velocity of an object.
Lesson
summary:

18. APPLICATION
1. How long will it take a driver to bring a jeepney travelling
50. 0m/s to complete the step if its acceleration is
0.500m/s?
2. The elevator in the land mark tower in Yokohama Japan
among the fastest in the world. They accelerated upward
at 3m/s² for 4s to reach their final speed. If these
elevator start from rest, what is the final speed?
3. A car travel at 90.0km/h. What is the acceleration in 3h if
it started from rest?

19. How can we relate acceleration from our daily
life?
Additional Activity

20. Define the following.
1. Motion Graphs
2. Position-Time graph
3. Slope
