## Newton’s Laws

This is manifested by the vibration mechanism of a catapult as well. As the toy trigger is being pulled, tension is applied to the trigger bar, relying on newton’s law. The ball is given a high pushing force by the gun, which makes it vibrate. this also depends on newton’s law. The system uses several scientific principles of operation, all of which revolve around the three Newton laws of motion. As the ball is fired from the catapult, it goes against gravity’s law to fly up in the air. this is an itinerary of Newton’s laws. As the ball lands on the ground, it is aided by gravity’s force to land down. The motion of the ball on the air forms a trajectory movement, which is also a function of Newton’s Laws. The ball is given traction power by the toy’s spring, which accelerates it towards the destination. The ball’s weight and the force with which the ball is pushed are the functions of the acceleration, which is the second law of Newton. As the child continuously shoots the ball with the toy from different destinations and obtains different results, he will effectively learn that the magnitude of the distance the ball will travel depends on the amount of force applied in triggering the gun. This will slowly sink into the head of the child as he or she prepares to understand that the distance traveled is a function of the acceleration given to the ball, which in turn is a function of both the weight of the ball and the amount of force released from the toy springs by pressing it down.

2. Apply common boundary conditions for the transverse vibration of beams to obtain natural frequencies.

The present examination concerns a disc of variable thickness of whose flexural stiffness $D$ varies with the radius $r$ according to the law $D=D_0 r^m$, where $D_0$ and $m$ are constants. The problem of finding boundary conditions for clasping this disc, which is inaccessible to straight observation, from the natural frequencies of its axisymmetric flexural oscillations, is measured. The problem in demand belongs to the class of opposite issues and is a very genuine difficulty of identifying boundary conditions. The search for the unknown conditions for clasping the disc is equivalent to finding the vectors of new Cond diseases stints. It is shown that this inverse problem is well-posed. .
