How does newtons law relate to a trebuchet?

Answer 1

The first of Newton's Laws describes the inertia that allows the projectile to leave the trebuchet. The second law describes the acceleration that the trebuchet applies to the projectile before it releases. The third law describes the reaction that occurs when the trebuchet is released, as the weight's force pushing down creates the reaction of launch.

Answer 2

It uses weight properties on one side of the trebuchet, force (N) and gravity! Here is how it works, imagine a wooden beam that is supported on it's center by something (Two or three other beams). If you tie one side with a very strong rope, and you put something very heavy on the other side, the beam will bend to the side that carries more weight (The side with a very heavy thing pulling it down!), now imagine a stone on the side with a rope, and now - imagine that you cut the rope! What happens? The weight of the stone quickly pulls one side of the beam that goes down (Gravity), and the other side goes very quickly up - throwing the stone (Ammo) high into the air. It also uses the physics of centrifugal force and elasticity of materials.

Answer 3

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

--So the load sits in the catapult until the catapult is launched, and then it moves (until it hits the ground).

II. The relationship between an object's mass m, its acceleration a, and the applied force F is F =

ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector.

The catapult can output a given amount of force depending on how far the bucket is cranked back. The mass depends on the load you put in the bucket. Knowing these two, you can figure out how much force on a given mass will generate any given acceleration (here, it's easier to describe it as a =

m/F)

III. For every action there is an equal and opposite reaction.

The catapult will experience exactly the same force as the thrown object but in the opposite direction. It will begin to move backwards.

Answer 4

a trebuchet is a lever with a counterweight on one end and the projectile on the other end with the fulcrum in the middle. The trebuchet's starting position is with the counterweight in the air and the projectile in a sling resting in a guide trough. When the counterweight is dropped (using gravity alone), the lever rotates pulling the projectile along the guide trough and flinging it up and over, releasing it at a high speed. The trebuchet was used in medieval times to storm castles and used large rocks to smash castle walls.

Answer 5

A taut string is pulled back and released to get an arrow to fly.

Doing work to pull the string back stores energy in the bow as elastic energy. When the string is released, it converts its energy into kinetic energy and transfers this to the arrow.

Answer 6

When the counterweight is sitting its storing energy but when it is released it is converted into kinetic energy.
