A. Directions: Write True if the statement is correct and False if not.
1. Gravity is a contact force that acts between two separate objects.
2. Gravity is a force exerted by the Earth which is equivalent to mass of an object.
3. Gravity on the Moon is less than the gravity on the earth.
4. Friction, unlike gravity, is a noncontact force.
5. Friction keeps object from sliding off surfaces.
6. The principle of gravity was discovered by Sir Isaac Newton.
7. Friction is the force that opposes the push of gravity on objects.
8. The lesser the mass of an object, the greater the pull of gravity on it.
9. Gravity keeps anything from going up.
10. Gravitational pull between objects increases as the distance between them decreases.
11. In some hydropower plants, dams are built to hold the water in artificial lakes.
12. The battery is the heart of any kind of power plant.
13. In geothermal plants, the mechanical energy of the Earth’s rock heats up water into stream.

okay, hanggang dito lang kaya kong ibagay kasi parang pinapasagutan mo na samin yung Buong Multiple Choice. at don't worry lahat yan ay tama dahil napag aralan ko yan at nasagutan at tama lahat pero hanggang 15 lang. Pag aralan mo yung iba at magbasa ka ng book! okay?!
