When a rifle is fired at a distant target, the barrel is not lined up exactly on the target. Explain why.

Answer :

Final answer:

The barrel of a rifle isn't pointed directly at a distant target as a measure to counteract the forces of gravity and air resistance. These forces influence the speed and trajectory of the bullet, often causing it to drop downwards. To ensure the bullet reaches the target, the shooter intentionally aims slightly above the target (trajectory compensation).

Explanation:

The barrel of a rifle isn't lined up exactly with a distant target due to the occurrences of gravity and air resistance. When a bullet is fired from a rifle, these forces act upon it. The force of gravity pulls the bullet downwards, causing a curved trajectory. This is also influenced by the bullet’s speed and angle at which it is fired. As for air resistance, it slows down the bullet, further causing it to drop down. In order to account for this drop, shooters aim the rifle slightly above the target - this is also known as a trajectory compensation.

Consider tossing a ball: It's similar with shooting a bullet. If you aim directly straight at your target and throw the ball, it will fall short due to the influence of gravity on it, and it might not reach the intended target. But if you aim slightly above the target, the ball is likely to reach the target since while it is being affected by gravity and comes downward, it will also move forward towards the target. This is the same principle with rifles and bullets.
