The document outlines the concept of acceleration, defining it as the rate of change in velocity and relating it to everyday examples. It includes several practical calculation examples and lessons on how to determine acceleration in various scenarios. Additionally, it emphasizes the distinction between acceleration and constant speed.

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.

Acceleration

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

5. How can we
say that an
object is
acceleratin
g?

6. Change

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?
