As a softball is hit high into the air and rises, it undergoes several changes in its motion. The key factors involved include gravity, air resistance, and the initial velocity imparted by the hit. Here's a general description of what happens:

Initial Launch:

  • When the softball is hit, it experiences an initial velocity in the upward direction. The force applied by the bat imparts kinetic energy to the ball.

Gravity's Influence:

  • As the softball rises, gravity acts on it, slowing down its upward motion. Gravity is constantly pulling the softball downward, counteracting its upward velocity.

Apex or Peak Height:

  • The softball reaches its highest point, known as the apex or peak height. At this point, its vertical velocity becomes zero before it starts descending.

Descent:

  • After reaching the apex, the softball starts descending due to the influence of gravity. Gravity accelerates it downward, and the initial upward velocity gradually diminishes.

Air Resistance:

  • Air resistance, or drag, also affects the descent of the softball. It opposes the motion and contributes to the slowing down of the softball as it falls.
