Me! a ball is thrown forward at 5 m/s. how would the path of the ball differ on earth than on the moon?
a. the ball would follow a curved path on earth but a straight path on the moon.
b. the ball would follow the same curved path on earth as on the moon.
c, the ball would curve down more sharply on earth than on the moon.
d. the ball would curve down on earth but curve up on the moon.
hurry!

Gravity is less on the moon, so the vertical acceleration is less. The ball curves down in both cases, but the curve is sharper on Earth, gentler on the moon.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
