Melanie watched the path a baseball followed after a pitcher threw it. She noticed that the ball traveled horizontally away from the pitcher, as well as downward toward the ground. What force caused the ball to accelerate in the downward direction when it was thrown?
electrical force
gravitational force
air resistance
applied force

Gravity
Average Speed
The graph shows distance and time the object traveled. Why this graph cannot used to determine average velocity?
the object was stationary for 2 hours
the speed of the object is constant
the direction of the object was not given
the average speed is unknown
