Who would have to overcome inertia to move the ball, a golfer or a soccer player?

Wouldn't it be both?

In order to overcome inertia and move the ball, both the golfer and the soccer player would have to apply force. However, the amount of force required and the type of movement may differ between the two.

To overcome inertia, an object needs an external force to act upon it. Inertia is a property of matter that refers to its resistance to changes in motion. The more massive an object is, the greater its inertia.

In golf, the golfer would need to overcome the inertia of the stationary golf ball initially, such as when teeing off or hitting a putt. The golfer uses a golf club to strike the ball and provide the necessary force to set it in motion.

In soccer, the soccer player would have to overcome the inertia of a moving ball, such as when kicking or passing the ball. The player applies force to the ball using their foot to change its velocity or direction.

Both the golfer and the soccer player need to generate enough force to overcome the ball's inertia, but the specific situation will determine the type of force required (stationary or moving ball) and the technique used (golf club or foot).
