* Gravity: The primary force acting on an object in vertical motion is gravity. Gravity constantly pulls the object downwards, causing its velocity to change.
* Acceleration: Due to gravity, the object experiences a constant downward acceleration (approximately 9.8 m/s² on Earth). This means its velocity changes over time.
* Upward Motion: When the object is moving upwards, gravity acts against its motion, slowing it down until it momentarily stops at its highest point.
* Downward Motion: As the object falls back down, gravity accelerates it, causing its downward velocity to increase.
Only in a hypothetical scenario where there is no gravity or air resistance would an object propelled vertically move at a constant pace.
