Answer 1

Explanation:

Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory.

_______________________________

Most projectile motion problems are set on Earth, which has a familiar gravity, although people can also calculate it for various objects on other planets, as long as the gravity is known. Simple problems also assume that air resistance and the Earth's rotation are unimportant, although in fact they can become issues with certain types of problems.

What is Projectile Motion?

• When a particle is thrown obliquely near the earth’s surface, it moves along a curved path under constant acceleration that is directed towards the centre of the earth (we assume that the particle remains close to the surface of the earth). The path of such a particle is called a projectile and the motion is called projectile motion.

• In a Projectile Motion, there are two simultaneous independent rectilinear motions:

1. Along the x-axis: uniform velocity, responsible for the horizontal (forward) motion of the particle.
2. Along y-axis: uniform acceleration, responsible for the vertical (downwards) motion of the particle.
