Question

Which of the following is not a projectile. (A) A bullet fired from the gun, (b) A rocket fired into space, (c) a ball thrown upwards and (d) a stone thrown horizontally from the top of the tower​

Answer 1

Answer:

c

Explanation:

because, when a ball is thrown upward it follows the linear motion...

Answer 2

Answer:

Correct option is: (b) A rocket fired into space

A rocket fired into space is not a projectile.

A projectile is any object that is thrown into space with only gravity acting on it. The main force acting on a projectile is gravity

Explanation:

When a particle is thrown obliquely near the earth's surface, it follows a curved path of constant acceleration to the earth's core. a particle's path is known as a projectile, and its motion is known as projectile motion.

When an rocket fired into space, it does not do so in a parabolic path. The motions of a rocket and a projectile are not the same. Because a projectile lacks a motor or rocket, it receives all of its momentum as it is launched hence it isn’t a projectile motion.

• A rocket or missile does have a motor/rocket on it to allow it to accelerate while moving and thus resist forces like gravity.

• A projectile is anything that flies through the air with only gravity acting on it.
• A rocket with an engine is not a projectile because the engine keeps the plane moving.

• Vertical and horizontal velocity are both present in projectiles.
• When a rocket takes off, it does not take a parabolic trajectory isn't a projectile movement.

All of the other options are projectile motion examples. As a result, A rocket fired into space the motion isn't projectile.
