The document describes various concepts related to motion including distance, displacement, speed, velocity, and acceleration. It provides examples of how to calculate each concept, such as calculating the average speed of a car that traveled 440 miles over 8 hours. Formulas are given for determining speed, velocity, and acceleration from values of distance, displacement, and time. A quiz with sample problems is also included to test understanding of motion concepts.
“HEAT”
Heat is a form of energy that flows from warmer bodies to colder bodies.
It is viewed as a form of energy that is transferred from one body to another due to a difference in temperature.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. Objective:
Describe the motion of an object in
terms of distance or displacement,
speed or velocity, and acceleration.
Motion in One Dimension
3. Motion is a change in position of an
object with respect to a reference point.
Enumerate
some
human
activities
that shows
motion?
4. Examples of Motion
People in the streets rush to get a ride
Children cannot keep still in their seats
Walking
Running
5. Draw it in your scratch
Example:
The lady walks 10 m to the north,
then she turns and continues walking
30 m due east. How far did the lady
walked?
6. Distance is the length of path traveled by a moving object.
It has scalar quantity which involves value and units
traveled.
7. Displacement (d) is the distance and the direction
along the straight line path from the initial to the
final point of motion. It could be the shortest
distance.
8. Example 1 of Displacement
What is the displacement of the cross-country team if
they begin at the school, run 10 miles and finish back at
the school?
Answer: The displacement of the runners is 0 miles.
While they have covered a distance of 10 miles,
they are not "out of place" or displaced. They finish
where they started. Round-trip motions always
have a displacement of 0.
9. A boy walks 10 meters east from A to B. Determine the
distance traveled and the displacement of the boy from her
starting point?
Example 2 of Displacement
Answer: Distance that the boy traveled is simply the
length of the path while the displacement not only the
magnitude of the path but also its direction.
10. Speed – describe the distance traveled per unit
time.
Who can still recall the formula of speed?
Speed = distance divided by
time
11. Speed – describe the distance traveled per unit
time.
Example 1. While on vacation, Liza’s Car
traveled a total distance of 440 miles. Her trip
took 8 hours. What was her average speed?
Given:
Find:
Solution:
12. Example 2. Jimmin loves taking care of homing
pigeons. He sent a note to his crush who lives 24
km away from his house. These birds fly at a rate
of 48.2 km/h. How long will the note reach
Jimmin’s crush?
13. Example 3. If Cathy, Myra and Eva all take
2.0 hours to walk from their house to their
school at a rate of 1.0 m/s, how far is their
school from the house?
14. Instantaneous Speed
During a typical trip to school, your car will undergo a series of changes in
its speed. If you were to inspect the speedometer readings at regular
intervals, you would notice that it changes often. The speedometer of a
car reveals information about the instantaneous speed of your car.
16. Velocity tells how fast a body moves and where it is going
(its direction).
It considers the displacement per unit of total time
traveled.
What is the formula of finding the velocity?
.
17. Example 1. Mr. Bean walks 7 km East in 2 hours and then
2.5 km West in 1 hour. What is Mr. Bean’s average velocity
for the whole journey?
Given:
Find:
Solution:
Velocity tells how fast a body moves and where it is going
(its direction). It considers the displacement per unit of total
time traveled.
18. Example 1. Mr. Bean walks 7 km East in 2 hours and then
2.5 km West in 1 hour. What is Mr. Bean’s average velocity
for the whole journey?
Given:
Find:
Solution:
Velocity tells how fast a body moves and where it is going
(its direction). It considers the displacement per unit of total
time traveled.
v = displacement_______ = 7 km – 2.5km = 1.5 km/h
total travel time 2 + 1
19. Example 2. A car travels along a straight road to the east
for 100 meters in 4 seconds, then go the west for 50
meters in 1 second. Determine average speed and
average velocity.
Given:
Find:
Solution:
20. Example 2. Answer:
Solution
Distance = 100 meters + 50 meters = 150 meters
Displacement = 100 meters – 50 meters = 50 meters, to
east.
Time elapsed = 4 seconds + 1 second = 5 seconds.
Average speed = Distance / time elapsed = 150 meters /
5 seconds = 30 meters/second.
Average velocity = Displacement / time elapsed = 50
meters / 5 seconds = 10 meters/second.
21. Acceleration occurs when velocities change due to
the change of its speed or direction.
It measures in meters per second squared.
What is the formula of finding the acceleration of the
moving object?
22. Acceleration occurs when velocities change due to
the change of its speed or direction.
It measures in meters per second squared.
Example 1. Martin rides a bicycle at 1.5 m/s south. Ten
seconds later, he is pedaling at 3.0 m/s south. What is
Martin’s acceleration?
Given:
Find:
Solution:
23. Acceleration occurs when velocities change due to
the change of its speed or direction.
It measures in meters per second squared.
Example 2. Calculate the acceleration of a car from rest
that travels at 24 m/s due east in 30 seconds.
Given:
Find:
Solution:
