  • Free Fall: Understanding Uniform Acceleration Due to Gravity
    A body falling freely from a height towards the Earth does not move with uniform velocity. It moves with uniform acceleration.

    Here's why:

    * Gravity: The primary force acting on the falling body is gravity. Gravity exerts a constant downward force, causing the body to accelerate.

    * Acceleration: Acceleration is the rate of change of velocity. Since gravity constantly pulls the body downward, its velocity increases over time.

    * Uniform Acceleration: The acceleration due to gravity (approximately 9.8 m/s²) is constant near the Earth's surface. This means the body's velocity increases at a steady rate.

    Key takeaway: While the acceleration of a freely falling body is uniform, its velocity is not. The velocity continuously increases as the body falls.
