Jul 04, 2019 · Anything that moves through air faces a number of forces; the flight of a golf ball involves two principal forces – lift and drag. While drag is a resistive force that slows the ball down as it moves, lift provides an upward force on the ball, making it go higher.

Jun 01, 2010 · The large drag force acts on the smooth ball, and the lift force on the smooth ball acts downward, as shown in Figure 5. Therefore, the flying distance of the smooth ball is short. On the other hand, the drag force on the golf ball is smaller than that on the smooth ball, and the lift force on the golf ball acts upward, as shown in Figure 5.

Explanation: As the air flows through the thin region between the funnel and the upper edge of the Ping Pong ball, its speed increases dramatically. As the air's speed increases, its pressure drops. With low pressure air on part of its upper surface, the ball experiences a net upward pressure force that's sufficient to support it against gravity.

If a 5-kg bowling ball is projected upward with a velocity of 2.0 m/s, then what is the recoil velocity of the Earth (mass = 6.0 x 10^24 kg). 34. 6. The Golf Range Gizmo gives you control over the initial velocity and angle of a projectile, and the experiment can take place in a vacuum (no air) or a more realistic situation with air. screen shot of the Golf Range Gizmo The figure above shows a case where we turned on the "trails" feature and launched the golf ball twice, once with air, and ...

balls until the standard surface dimple pattern was achieved. These dimples hold little pockets of air and serve to reduce the drag as the ball flies through the air. They also create a thin turbulent boundary layer of air over the surface of the ball, which in turn reduces air resistance and helps the ball to travel a farther distance than a smooth ball would. Golf Swing The golf swing involves two main components – first is the Feb 09, 2015 · Why would a ball curving one way in the air go further than a ball curving the other way? After all, if we conducted a test in a very controlled environment and all the factors other than curvature through the air were the same, we would find that draws and fades travel the exact same distance.
