SUMMARY
In free-fall, the acceleration due to gravity is consistently +9.81 m/s² when measured in the downward direction on Earth. In the context of two-dimensional kinematics, gravity acts on any object thrown in the air as -9.81 m/s², indicating its downward acceleration. Regardless of the object's motion, gravity remains a constant force acting downwards at this rate. Understanding these principles is essential for solving problems related to projectile motion and free-fall dynamics.
