How does arm length affect throwing distance?

How does arm length affect throwing distance?

Because shorter forearm, wrist, hand and finger bones have less inertia to overcome, a baseball pitcher can move them faster through release. As a result, with the same amount of force applied, a baseball pitcher with shorter bones in his lower pitching arm can achieve higher release velocities.

How do you make a catapult more accurate?

Wind the string or rope tighter. Put a piece of wood across the base of the catapult to keep it strong, so you can wind even tighter. Lengthen the swing arm of the catapult or move the cup up or down the length to different spots. Move the crossbar up or down, or add pieces of wood to it to change the trajectory angle.

What is the biggest catapult ever made?


How do you build a catapult?

Simple craft stick catapult:

  1. Stack five craft sticks together and wrap a rubber band around each end.
  2. Stack two craft sticks and wrap a rubber band around only one end.
  3. Slide the five sticks in-between the two sticks, as shown.
  4. Wrap a rubber band where the two sections meet to hold the catapult together.

What angle is best for a catapult?

45-degree angle

What factors could affect a catapult?

What Variables Affects Catapult Accuracy?

  • Distance from the fulcrum.
  • Force behind launch.
  • Today’s Objective:
  • Weight of the Projectile.
  • Angle of Release (pull back)
  • pullback = launch time.
  • Durability of Construction.
  • Accuracy vs. Precision.

What is the range of a trebuchet?

300, 180, and 120 feet

Why is a long arm better for throwing a light ball?

Longer arms can also help throw a ball faster and farther due to the increased centrifugal force they can generate during the throwing motion, according to The Sport Journal. Regardless of the arm length, however, proper warmups and throwing mechanics are critical to reduce the risk of injuries.

What kind of simple machine is a catapult?


What materials do you need to build a catapult?


  • Eight craft sticks (popsicle sticks)
  • Four or five sturdy rubber bands.
  • Glue.
  • Plastic bottle cap to hold a cotton ball.
  • Cotton ball (If you do not have any available, you can make a small ball by crumbling some paper.)
  • Small open area (One square meter will do.

How do you make a simple catapult out of pencils?

  1. Step 1: Make a Pencil Triangle. Arrange 3 pencils into an equilateral triangle.
  2. Step 2: Reinforce the Triangle.
  3. Step 3: Make Another Triangle.
  4. Step 4: Connect the Supports (At the Top)
  5. Step 5: Connect the Supports (At the Bottom)
  6. Step 6: Attach the Pivot.
  7. Step 7: Make the Catapult.
  8. Step 8: Attach Catapult.

How much weight can a trebuchet throw?

First, it can handle heavier projectiles. A catapult’s maximum weight tops out at about 180 pounds; trebuchets top out at about 350. Second, compared with a torsion engine, it’s a fairly robust machine. Lastly, for a given weight of stone, the trebuchet has a longer range.

How does mass affect distance?

Objects with greater masses are found to be affected more by gravity, and therefore don’t travel as far when launched. Also, as shown by Newton’s Second Law of Motion, if two objects are given the same force, the lighter object will accelerate more, and therefore cover more distance.

How do you find the range of a catapult?

With an understanding of the basic functions of a catapult, one can use the following formulas to ascertain measurements pertaining to its operation.

  1. Height = ( v sinθ )² / 2g.
  2. Time of flight = 2 v sinθ / g.
  3. Range or horizontal distance covered = v² ( sin 2θ ) / g.
  4. assumes zero loss.

How do we use catapults today?

Catapults were used to throw hand grenades across No Man’s Land and into enemy trenches. Now catapults are used in target practice to shoot clay pigeons in the air, to launch food at siblings, and the most common use to launch planes into the air.

Does the angle of a catapult affect the distance?

The angle at which the throwing arm is pulled back to will affect both the distance the projectile will travel and also the height that it reaches when in the air.
