  1. Answer:

    Step-by-step explanation:

    Acceleration due to gravity is the rate at which an object changes its velocity due to the force of gravity.On Earth, the average acceleration due to gravity is -9.81 m/s².The acceleration due to gravity is ALWAYS negative.  Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s², regardless of the direction.

    The acceleration is negative when going up because the speed is decreasing.  The acceleration is negative when going down because it is moving in the negative direction, down.  Even at the top of the path where the instantaneous speed is 0 m/s, the acceleration is still -9.81 m/s².
