All three play a part. The first applies as the arm swings and launches the projectile. The arm continues to move until it is stopped by the retaining bar and the projectile continues to move until gravity pulls back down or it impacts a structure. The second law is shown by the projectile. A big heavy rock goes slow, a small light rock flies fast. The third comes into play as the catapult launches the projectile it pushes down on the ground and slightly backward. The projectile itself uses the third law when it impacts.
Newton's first law of motion was the law of inertia. When an object is in motion, it stays in motion. When an object is in rest, it stays in rest.
from this law we can relate 1st and 3rd law : f = ma from this we can say that until and unless force acts on a body it will remain in motion or in rest. when we hit a wall with our hand the wall gives equal and opposite magnitude to our hand fa1m1 = -fm2a2
Newton's first law is sometimes called the law of inertia.
A catapult demonstrates Newton's second law of motion by showing how the acceleration of the projectile (object being launched) is directly proportional to the force applied by the tension in the catapult's arm (F=ma). This means that the larger the force applied to the arm, the greater the acceleration of the projectile, leading to a more powerful launch.
The first law of motion follows from the second, for the case that the net force is zero.
The first law states that with no forces involved, a body will remain at rest, or at fixed velocity in a straight line.

The Concept of Inertia is defined in Newton's First law of Motion.
Inertia is a sporting example of newton's first law of motion.
It is the first law of motion.
Isaac Newton, he discovered: -Newton's First Law of motion. -Newton's Second Law of motion. -Newton's Third Law of motion.
