Velocity:
* Direction: Upwards (positive if you define "up" as the positive direction).
* Magnitude: The speed of the object as it moves upwards. This will decrease as the object moves upwards due to gravity.
Acceleration:
* Direction: Downwards (negative if you define "up" as the positive direction).
* Magnitude: The acceleration due to gravity, which is approximately 9.8 m/s² near the Earth's surface. This means the object's upward velocity will decrease by 9.8 meters per second every second.
Key Points:
* Gravity: The primary factor influencing the upward motion is gravity. It acts constantly to pull the object downwards.
* Initial Velocity: The object's initial upward velocity will determine how high it travels.
* Peak: Eventually, the upward velocity will reach zero at the object's highest point. Then, the object will start falling back down.
Example:
Imagine you throw a ball straight up into the air.
* Initially: The ball has a positive upward velocity.
* As it rises: The velocity decreases (becomes less positive) due to gravity's pull.
* At the peak: The velocity is momentarily zero.
* As it falls: The velocity becomes negative (downward) and increases in magnitude.
