Putoamisliike

Putoamisliike, often translated as "falling motion" or "free fall," refers to the movement of an object under the sole influence of gravity. In ideal physics scenarios, this motion is characterized by a constant acceleration downwards. The acceleration due to gravity, denoted by 'g', is approximately 9.81 meters per second squared near the Earth's surface. This means that for every second an object falls, its downward velocity increases by roughly 9.81 m/s.

The concept of putoamisliike is fundamental to understanding projectile motion and orbital mechanics. While in everyday experience, air resistance often plays a significant role, the idealized model of putoamisliike simplifies the analysis by neglecting such forces. This allows for the derivation of kinematic equations that describe the position and velocity of an object at any given time during its fall.

Galileo Galilei was a pioneer in studying falling objects, famously demonstrating through experiments that objects of different masses, when dropped from the same height in a vacuum, would hit the ground simultaneously. This contradicted earlier Aristotelian physics, which posited that heavier objects fall faster. The principles of putoamisliike are crucial in fields ranging from engineering and astronomy to everyday phenomena like the trajectory of a thrown ball.
