Which one of the following accurately describes the force of gravity?

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

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
