Question
An object is shot vertically upward. While it is rising: Group of answer choicesits velocity and acceleration are both decreasingits velocity and acceleration are both upwardits velocity is downward and its acceleration is upwardits velocity and acceleration are both downwardits velocity is upward and its acceleration is downward
Solution
The correct answer is: its velocity is upward and its acceleration is downward.
Here's why:
-
When an object is shot vertically upward, it initially has an upward velocity (the speed it was shot at).
-
However, due to gravity, it is constantly being slowed down. This slowing down is an acceleration in the opposite direction of its motion. In this case, the acceleration is downward.
-
So, while the object is rising, its velocity is upward (it's still moving up, just slower and slower) and its acceleration is downward (it's being slowed down by gravity).
