Which are the effects of gravity on objects on the surface of Earth? Choose two correct answers.

Gravity pulls objects near Earth toward Earth's center, so objects fall in that direction. Near Earth's surface, gravity causes an acceleration of about 9.8 meters per second each second; it does not mean objects move at a constant speed of 9.8 meters per second. Earth and an object also pull on each other with equal strength, so choices C and D are incorrect.
