Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Whether an object is heavy or light, gravity affects it. Gravity pulls things down to Earth. (page 7)
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Because the downward force on an object is equal to its mass multiplied by g, heavier objects have a greater downward force. Heavier objects, however, also have more inertia, which means they resist moving more than lighter objects do, and so heaver objects need more force to get them going at the same rate.

Detailed explanation-2: -The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.

Detailed explanation-3: -Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass.

Detailed explanation-4: -Gravity is the force that pulls all objects in the universe toward each other. On Earth, gravity pulls all objects “downward” toward the center of the planet.
