Freefall is the motion of an object under the influence of gravity alone, meaning that no other forces, like air resistance, are acting on it. During freefall, an object accelerates downward at a constant rate due to Earth's gravitational pull, which is approximately $$9.81 ext{ m/s}^2$$. This concept is crucial for understanding how objects move in projectile motion and further applications of Newton's Laws, as it emphasizes the role of gravity in determining an object's trajectory and speed.
congrats on reading the definition of freefall. now let's actually learn it.
