The document discusses the force of gravity and its effects. It explains that gravity is a downward pulling force that attracts all objects on Earth toward its center. It causes things thrown up to fall back down, and makes downward movement faster than upward movement. Gravity is responsible for many phenomena we observe, such as leaves falling from trees, objects slipping from our hands, and kites falling when the wind stops blowing. It establishes our weight and keeps us and everything on Earth from floating off into space.

1. GRAVITY

2.  Have you ever seen dried leaves falling from
the tree?
 The wind blows and carries the leaves, taking
them to different locations.
 Sometimes, water carries the leaves to other
places.
 However, no matter where these dried leaves
are carried, they are eventually land on the
ground.
 There are forces that move the leaves up, but
the force of gravity let them rest on the
ground.
 Why do you thinks so?
 Why do things thrown up in the air fall back
to the ground?

3. THE FORCE OF GRAVITY

4. - Try to jump as high as you can.
- No matter how high you jump, you will surely
land on the ground.
- The force that acts on falling is called gravity.
- noncontact force, which means that the
object acted upon is at a distance.
- gravitational force that acts on an object
pulls the object down.

5. - Everything on Earth is pulled by gravity.
- This downward pull keeps people and the
things around from falling off the planet Earth.
- It also holds the bodies of water on the surface
and the atmosphere around.
- All things on Earth, even air and water, are
pulled by gravity and therefore stay and do
not float or fall out in space

6. - Observe your surroundings.
- Find out the effects of gravity on the objects
around you.
1. Hanging objects
2. Objects that slip on your hands
3. If you throw a ball or a stone upward
- Hanging objects are directed downward
because of gravity.
- Objects that slip on your hands fall downward.
- If you throw a ball or a stone upward, it goes
down to the ground.

7. - In most cases, the force of gravity seems to
stop objects from rising.
- Moving an object to a higher place is more
difficult than bringing it down.
- Ex:
- Going down the stairs is easier than going
up
- Climbing up a hilly area is more difficult
than going down, body tends to bend
forward and make small steps with
difficulty, but you move faster when going
down
- Gravity does not only cause objects to move
downward but also makes the downward
movement faster.

8. - Big rocks from the top of the mountain roll
down to the hillside swiftly.
- Even hanging high cliffs fall to the ground.
- In the same way, from the top of a slide, you
move downward fast.
- These are all because of the pull of gravity.
- A pulling force is exerted on the objects; thus,
they move downward, toward the earth.

9. - What do you think will happen to birds when
they suddenly stop flapping their wings as they
fly?
- Flapping their wings pushes them to move
higher, but once they stop, they will surely
fall to the ground because they will pulled
by gravity.

10. - In flying a kite, you need the wind
to blow and raise the kite up in the
air.
- However, when the wind stops
blowing
- The kite goes down
- The force of the wind blows it up,
while the force of gravity pulls it
down.

11. • Gravitational force gives you your weight here on earth.
• The force of gravity is equal to your weight.
• If you weigh 40 kg, the pull of gravity on your body is also equal to 40 kg.
• Book weighs 2.5 kg, the pull of gravity on the book is equal to 1.5 kg
• Weigh yourself using a weighing scale and discover how much the pull of gravity is
on the body.

13. • Keeps everything down, including people
• If earth has no gravity, you and everything around you will float, make doing
different activities difficult
• At home, the force of gravity and the pumping system works hand in hand.
• Many houses have a water tank, which is usually kept in a high place in
the house and is filled with water by pumps operating in the basement or
on the roof.
• The water is then fed to the different parts of the house by gravity.
• The water flows down to the pipes and faucets in the ground level.

14. • Hanging or loose objects are shaken or pushed, they might break and fall
because of gravity.
• It can cause danger, might accidently it and harm people.
• Need to handle breakable materials carefully because once they slip of
the hands, they would turn into pieces and become useless.
• Careful when going to a higher place, say when you go up the stairs, to
prevent that may injure your body,

15. • Gravity may cause movement that results in accidents. You can avoid such
accident by doing the following:
1. In case of natural disasters such as earthquakes, avoid staying under
hanging objects. These objects might fall down because of gravity and hit
your body.
2. Because gravity pulls you down, be extra careful in doing certain activities.
For example, never sit on a weak chair or furniture that cannot carry your
weight. A weak chair will naturally cause you to fall and may even result in
injuries.
