# What is the best amount of water for a 2 liter bottle rocket?

## What is the best amount of water for a 2 liter bottle rocket?

A: The simple answer is something less than half full. Since the compressed air stores the energy, and the water provides momentum, both are needed. Fill perhaps 40-50% of the motor volume with water.

## What is the best angle to launch a water rocket?

45 degrees
A launch angle of 45 degrees maximizes the range (see the figure below). When a projectile is launched, it has both a vertical velocity and a horizontal velocity. (NOTE: If the wind velocity is high and coming from behind, then the rocket may go further if the angle is increased above 45 degrees.

## How do you make a pop bottle rocket launcher?

Fill bottle with 1 liter of water. Slide bottle down onto launch tube. Lock bottle in place with ¾” coupler. Slide string under the cross bar in the base, weigh it down with tent pegs or rocks • Attach bike pump to valve • Pump air into the bottle until you reach 40PSI.

## What is the best fuel for the water bottle rocket?

The cap of the bottle must be drilled to produce a nozzle for the rocket. Do not make the nozzle hole smaller than 3/8 inch because this can produce excessive pressure in the bottle during combustion resulting in explosion of the bottle. Use only rubbing alcohol (isopropyl alcohol) for the fuel.

## What is a projectile launcher?

Launcher The Projectile Launcher is used to investigate important concepts in two- dimensional kinematics. A steel ball placed in the launch barrel can be projected for different launch velocities and launch angles. An easy-to-use dial allows you to set the desired launch angle.

## How do you make a simple projectile?

How to Make a Projectile Launcher

1. Step 1: Supplies. 1 pencil 1 rubber band 1 binder clip a lot of paper.
2. Step 2: Preparing the Clip. tie the rubber band around the binder clip.
3. Step 3: Put the Binder Clip on the Pencil. open the two metal prongs and slide the clip on the pencil.
4. Step 4: Make Ammo.
5. Step 5: How to Shoot.

## Why does a bigger bottle help increase thrust?

As the bottle pushes out the air, the air pushes the bottle upwards (Newton’s Third Law of Motion). Increasing the thrust (adding more pressure to the bottle) increases the acceleration. We see the bigger acceleration as a higher flight.

## What are the different types of projectile launchers?

PASCO offers two different projectile launchers. Our full-sized Projectile Launcher offers selectable ranges of 1.2, 3, or 5 m and launch angles from 0° to 90° and our Mini Launcher is great for table top experiments with ranges of 0.5, 1, and 2 m and the ability to fire it downward with launch angles from -45° to 90°.

## Can I use the ballistic pendulum with the projectile launcher?

Our standalone Ballistic Pendulum is used with the Projectile Launcher. It is available by itself (No Launcher) or as a set that includes the Projectile Launcher. The probeware option is to use our Ballistic Pendulum Accessory or Mini Launcher Ballistic Pendulum Accessory along with our Rotary Motion Sensor.

## What is included in the projectile launcher smart gate system?

Save with the Projectile Launcher Smart Gate System — a complete package that includes our Mini Launcher, a Smart Gate and Projectile Mounting Bracket, a Table Clamp, and a Steel Mounting Rod. The Photogate head can also be daisy chained to a Smart Gate.

## How do you measure launch velocity in Rocket League?

Add optional Smart Gate to measure launch velocity. The “gun” is aimed directly at the target. Although the target “drops” the moment the projectile is fired, the ball still hits the target since the ball falls with the same acceleration.
