* Constant acceleration: The object experiences a constant acceleration due to gravity, denoted by 'g', which is approximately 9.8 m/s² near the Earth's surface. This acceleration is always directed downwards, towards the center of the Earth.
* Increasing velocity: As the object falls, its velocity increases linearly with time. This means that the object's speed gets faster and faster at a constant rate.
* Neglecting air resistance: In ideal conditions, we assume that there is no air resistance acting on the object. This allows us to focus solely on the effect of gravity.
Key points:
* Initial velocity: The initial velocity of the object can be zero (if it starts from rest) or non-zero (if it is thrown downwards or upwards).
* Trajectory: The object follows a straight line path downwards, assuming negligible air resistance.
* Equations of motion: The motion of a freely falling object can be described using the equations of motion for uniformly accelerated motion, such as:
* v = u + at
* s = ut + (1/2)at²
* v² = u² + 2as
Important Note: In real-world scenarios, air resistance plays a significant role in the motion of falling objects. This resistance increases with the object's speed, eventually reaching a terminal velocity where the force of air resistance balances the force of gravity.
