Key Concepts

Kinematics

Kinematics involves the study of motion using equations that relate displacement, velocity, acceleration, and time. In free-fall scenarios, these equations (such as v = u + at) are instrumental in determining the speed acquired by an object after a specific time, integrating both the effects of initial velocity and gravitational acceleration.

Gravitational Acceleration

This is the nearly constant acceleration (approximately 9.8 m/s² near the Earth’s surface) with which objects accelerate when falling freely under gravity. Its uniform value allows us to predict the speed of objects in free-fall irrespective of their mass, assuming negligible air resistance.

Free Fall

Free fall describes the motion of objects that are falling solely under the influence of gravity, without any propulsion or air resistance interfering. In free fall, all objects accelerate at the same rate defined by gravitational acceleration, making the motion highly predictable.

Initial Velocity

Initial velocity is the speed of an object at the start of its motion. In problems where an object is dropped from rest, this velocity is zero, making calculations straightforward. However, if the object is not released from rest, its initial velocity must be taken into account, which alters the final speed after a given time.
