Physics Behind Darts
The game of darts as we know it has been played for over 100 years since it was created in 1896. To play the game, participants throw small pointed spears known as darts at a numbered circular object. Considered by some as a game of chance, it was soon elevated to a game of skill after being challenged in court. With over a 1000 ranked dart players throughout the world, the game of darts is all physics and no chance.

Amazing But True!
- The distance a competitor should be from the dartboard according to the World Darts Federation is 2.37 m. If you were to release the dart at the same vertical distance as the bulls-eye, assuming an average speed of 17.9 m/s, you can easily calculate how much the dart will drop before it hits the dartboard.
- If the bulls-eye has a diameter of 0.012 m, you would have to aim slightly above the bulls-eye to score a perfect shot. It is important to note that the slower your throw is, the higher you will have to aim the dart to account for the amount of time the dart will be under the influence of gravity.

Using the information provided above, answer the following questions.
- What force is the main culprit that affects the vertical drop in the dart?
- Explain why the air resistance is considered negligible in this case.
- If you had to release the dart at the center of the bulls-eye, what could you do to ensure that the effects due to gravity would be negligible and that you would hit your target?
