Question

. In which of the following situations would an object be accelerated? I. It moves in a straight line at constant speed. II. It moves with uniform circular motion. III. It travels as a projectile in a gravitational field with negligible air resistance.

Answer 1

III. It travels as a projectile in a gravitational field with negligible air resistance.

Step-by-step explanation:

In this case, the body is under the effect of a force, therefore, it accelerates. This is due to the gravitational field, which is independent of its mass. Therefore, the body is under the effect of the acceleration of gravity, which is constant throughout the trip.
