Accurately describes the force of gravity? a. the gravity acceleration is in the same direction as the force of gravity, and thus toward the center of the earth. b. the gravity acceleration is in the same direction as the force of gravity, and thus away from the center of the earth. c. the force of gravity is slightly lower at the bottom of a mountain than it is at the top. d. the gravity acceleration has no effect on a body moving in directly the opposite direction of the force of gravity.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
