1. The Earth's ______ force is the reason why things
fall.
2. ______ is a natural phenomenon wherein all things
with mass or energy are attracted to one another.

Describing Gravity
Gravity is a force of attraction that exists between any
two objects.
Gravity is a force that tries to pull two objects toward
each other.
Gravity is a natural phenomenon wherein all things
with mass or energy are attracted to one another.
The force of gravity towards an object depends on two
things: the mass of the objects and the distance between the
objects.
Greater mass results in greater force; greater distance results
in smaller force. This means that the more mass they have
and the closer the objects are, the greater is the force of
gravity.
On Earth, gravity pulls all objects to Earth’s center. All objects
in the universe attract each other, therefore gravity acts on all
objects in the universe.
The Earth’s gravity is the reason why things fall
down rather than up and what keeps you
walking on the ground instead of flying off into
space. All objects with a mass will experience a
force of gravity which is directed “downward”
toward the center of the earth.
Weight is a measure of the force of gravity
pulling down on an object.
Study the illustration below:
The force that is present while the girl is trying
to slide across the skating rink is friction.
The force that pulls the girl to the ground as she
fell is called gravity.
Other examples involving gravity or gravitational force are
shown below:
Other examples involving gravity or gravitational force are

Directions: Read the following statements carefully. Write T if the
statement is True and F if it is False in your Science activity
notebook.
_________ 1. Gravity helps the Earth to stay in orbit around the Sun.
_________ 2. Gravity is the attractive force that exists between any
two objects.
_________ 3. Gravity is the reason why leaves fall from the tree.
_________ 4. How much gravity an object has depends on its mass.
_________ 5. Mass is a measure of the force of gravity pulling down
on an object.
Indicate if the friction has desirable or undesirable effect. Write D
for desirable and U for undesirable. Answer in your activity
notebook.
____1. Wet roads are dangerous for travelling vehicles.
____2. Friction produces heat that can be used for cooking.
____3. A rubber placed at the edge of the staircases helps in avoiding
accidents.
____4. Applying wax to the surface makes it easier to move heavy
objects.
____5. Smooth floor on playgrounds can cause more accidents on
children.
Gravity is very important to all of us. Without
gravity, we could not live on Earth; instead, all
the objects will be floating into the space.

DAY 3
How does the gravitational force affect
people’s lives? Do you have any idea
of finding ways to minimize its effect?
In everyday life, we can observe the gravitational force and its
effects on the objects. Everything that goes up on Earth comes
down. Gravitational force is the force of attraction between all
masses in the universe, especially the attraction of Earth’s mass for
bodies near its surface. There are factors that affect the movement
of the objects as they fall such as the air, weight and distance.
Objects falling on Earth pass through air. The movement of the
falling object is affected by the air. It can slow down the movement
of an object.
The weight of an object can greatly affect the gravitational force of
attraction. The heavier the object, the faster it moves to the ground.
The gravitational force acting on an object is affected by
distance. The more distant the object from the earth, the
less gravitational force of attraction. The closer the objects
from each other, the greater are the gravitational force.
When the distance increases, the gravitational force
decreases.
Activity 1

1. Which object consistently hits the floor first?
2. When you dropped two different objects, which

It was Sir Isaac Newton, an English mathematician and
physicist who discovered gravity when he saw a falling apple
while thinking about the forces of nature.
• Gravity is the force that attracts planets, bodies and
elements towards each other.
• Gravity only pulls; it never repels.
• Gravity is weaker the farther an object is.
• Gravity causes everything to fall at the same speed.
This is why balls with different mass hit the ground at the
same time.
Put a check () on the space if the activity is
affected by the gravitational force and X if not.

  • 46. DAY 4
  • 47. Have you experienced mountain climbing? Why is it hard for you to go up the mountain than going down? What do you think made it hard for you to do so?
  • 48. In everyday life, we can observe the gravitational force and its effects on the objects. Everything that goes up on Earth comes down. Gravitational force is the force of attraction between all masses in the universe, especially the attraction of Earth’s mass for bodies near its surface. There are factors that affect the movement of the objects as they fall such as the air, weight and distance. Objects falling on Earth pass through air. The movement of the falling object is affected by the air. It can slow down the movement of an object. The weight of an object can greatly affect the gravitational force of attraction. The heavier the object, the faster it moves to the ground.
  • 49. The gravitational force acting on an object is affected by distance. The more distant the object from the earth, the less gravitational force of attraction. The closer the objects from each other, the greater are the gravitational force. When the distance increases, the gravitational force decreases.
  • 50. Direction: Write the effects of gravitational force in the graphic organizer and write your answers in your activity notebook.
  • 51. Directions: Choose the letter of the correct answer. Write the letter of your answer on a separate sheet of paper. 1. What can make objects move fast and stop? A. energy B. force C. gravity D. motion 2. If you climb the stairs, you will experience difficulty to reach the highest part. Why? A. You go against gravity. B. You go with the gravity. C. Gravity pushes you up. D. Gravity has an upward force.
  • 52. 3. What do you call the pull of attraction towards the center of the earth? A. force B. gravity C. kinetic friction D. frictional force 4. What do you call the pull of gravity on any object? A. mass B. weight C. motion D. newton 5. What would happen to objects and people if there is no gravity? A. The objects and people would not move or remain stationary. B. The objects and people would neither rise nor fall, or they would just float. C. The objects and people would eventually drift away and float off into space. D. The objects and people will move downward and will remain still on the ground.

  • 54. It was Sir Isaac Newton, an English mathematician and physicist who discovered gravity when he saw a falling apple while thinking about the forces of nature. • Gravity is the force that attracts planets, bodies and elements towards each other. • Gravity only pulls; it never repels. • Gravity is weaker the farther an object is. • Gravity causes everything to fall at the same speed. This is why balls with different mass hit the ground at the same time.
  • 55. Read the questions carefully and write the letter of the correct answer in your activity notebook. 1. Which of the following statements does NOT tell about the effects of gravitational force on objects? A. The more distant the body from the earth, the lesser is the gravitational force of attraction. B. Gravitational force pushes the objects upward. C. Gravitational force is greater when the objects are closer together. D. The farther you are from earth, the lesser your weight. 2. Why is it difficult for us to go up in a mountain than go down? A. We are moving against gravity. B. We are pulled by the wind. C. We are moving towards gravity. D. None of the above
  • 56. 3. Which of these will have the strongest gravitational pull on Earth? A. a baby B. a drinking glass C. a half sack of rice D. an elephant 4. Without air resistance, all objects fall at the same rate. A. True B. False C. Maybe D. Neither True or False 5. The gravity between two objects increases as the distance between them ___. A. decreases B. increases C. neutralizes D. stabilizes
