Activity 2: TRUE or FALSE
Directions: Write TRUE if the statement correctly describes friction and gravity and
FALSE if it is incorrect. Write your answer on the space before the number.

1. When a car goes upward on a hill, it moves against gravity.
2. Friction is a force that pulls all objects down to Earth’s center.
3. Gravitational pull is less on the moon than on Earth.
4. If there is no air resistance, objects dropped from the same height will hit the ground at the same time.
5. Isaac Newton observed that an apple falls from a tree because of gravity.
6. The moon’s gravitational pull causes seawater to rise that results in a low tide.
7. A ball that is thrown upward will eventually fall to the ground because of frictional forces.
8. Any object falling without air resistance is in the state of free fall.
9. The sun’s gravitational pull keeps the planets in the solar system in their orbits.
10. Earth’s gravity acts more strongly on an object located on top of Mt. Everest than an object located at sea level.

Explanation:

An object moves against a gravitational force when it is moving away from it. An example of this is the given. Cars go against the gravity of the Earth when it moves uphill and vice versa.
Gravity is the force that pulls all objects down to Earth’s center. Friction occurs when two surfaces make contact with each other.
Moon's gravitational force is equivalent to $1.62m/s^{2}$ , while Earth's is equal to $9.807 m/s^{2}$ . Therefore, the Moon's gravitational pull is less than Earth's.
Earth provides the same acceleration to every object having different masses. Even with that said, air resistance plays a role in making it impossible for things on our planet to land at the same time when thrown at the same heights. The less heavy the object is, the more energy air resistance slows it down as it descends. On the other hand, the Moon, which has no air resistance, allows objects to fall at the same time at the same height no matter what mass they have.
Sir Isaac Newton was the one who observed an apple(s) falling from a tree(s) that gave him an idea to come up with the Laws of Gravity. He wasn't necessarily bonked by an apple though. It happened at Woolsthorpe Manor when an outbreak of the bubonic plague had spread.
The Moon’s gravitational pull causes seawater to rise which results in a high tide. It attracts the bodies of water on Earth to go towards it. However, the Earth's gravitational pull is much stronger than Moon's, leading to a disturbance in our oceans and seas.
A ball that is thrown upward will eventually fall to the ground because of gravitational forces. The applied force towards the object led to an upward motion. But the gravity of the Earth is greater than the force applied, leading to the downward motion.
An object that is only actuated only by gravity is in a state of free fall.
The Sun's gravitational pull attracts the planets and other celestial planets towards itself, leading to a circular motion around it. The path these objects go through is called an orbit. Without the Sun, the other heavenly bodies would have gone rogue.
Earth’s gravity acts more strongly on an object located at lower places than higher ones. The closer the objects are together, the stronger the gravity is.
