Gravity is a contact force that acts between two separate objects.
2. Gravity is the force exerted by the Earth which is equivalent to the 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 objects 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.
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.

Answer 1

Answer:

please mark me as brainliest answer.

Answer 2

Answer:

ANSWERS ARE IN THE DESCRIPTION.

Explanation:

1. False (It is a non-contact force that is exerted on the body from the distance separated from each other).Gravity is said to be a non-contact force because the gravitational force is exerted by one mass on another from the distance separated between them and without being in physical contact. All the objects having mass are bounded to one another by the gravitational pull of attraction. Gravity is a central force because it is directed towards the center of the objects.
2. True
3. True
4. False (Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.)
5. True
6. True
7. True
8. False(Lesser the mass of object lesser will be the gravitational pull)
9. True ( ACTS DOWNWARDS)
10. True ( F=GMm/r² where F be the gravitational force m be the mass of objects r be the distance between objects. Gravitational force is inversely proportional to square of distance between them.)
