Question

Which of the following is not a projectile?

• A. An aircraft taking off
• B. A ball is thrown horizontally from a roof
• C. A bullet fired from a rifle
• D. A football kicked by a player​.

Answer 1

The correct option is A

An aircraft taking off

The explanation for the correct option:

Projectile Motion:

1. A projectile is any object that is thrown into space with only gravity acting on it.
2. Gravity is the most powerful force acting on a projectile.
3. When a particle is thrown obliquely near the earth's surface, it follows a curved path with constant acceleration to the earth's center. The path of a projectile will be parabolic.
4. When a plane takes off, it does not take off in a parabolic trajectory. As a result, there is no projectile motion.

Hence, Option(A) is correct.
