Why does a ball that is hit harder fly farther?

A. The pitcher has put a lateral spin on the ball.
B. Air pressure is acting on the surface of the ball.
C. The hitter has put a lot of external force on the ball.
D. The force of gravity acts to pull the ball down.

Respuesta :

C. The hitter has put a lot of external force on the ball.

Explanation:

  • When high external force is applied to a ball that is hit harder, it flies farther
  • Three forces act on the baseball in flight - lift, drag and weight
  • Weight - directed towards earth's center
  • Weight can be determined by Newton's laws of gravitation
  • Drag - When the ball moves through air, a resistance force (drag) is applied to its motion
  • Drag - Directed along and opposite to flight direction of the ball
  • Lift - aerodynamic force perpendicular to the flight direction
