Explore projectile motion with this 100% safe, chemical-free air-powered projectile. Flies straight and true with minimal wind effect and with a consistent, repeatable initial velocity - important for students testing predictions.
This air-powered projectile is sure to send your students' imaginations soaring.
Solid-fuel and water rockets just have too many variables for an accurate study of Newton's Laws. So explore projectile motion with this 100% safe, chemical-free air-powered projectile.
Accurate and repeatable to an amazing degree, thanks to the hard-plastic chassis, this missile flies straight and true with minimal wind effect. Since it takes off at the same velocity every time, your outcome is always precise and consistent - important for students testing predictions, who'll reap rewarding results.
And it's a breeze to use. All you do is pressurize the launch chamber with an ordinary bicycle pump. When the pressure is high enough to pop off the Thrust Washer, the projectile blasts into the sky. Each projectile comes with three different Thrust Washers;
This allows you to vary launch speed for different experiments. You can even use a launchpad with various launch angles. Then your students can use Newton's Laws to predict where the projectile will land!
Here's a lesson you can try with the air-powered projectile:
- Shoot the projectile straight into the air and measure how long it takes to land. (In this example, let's use 6 seconds).
- Divide that time by 2 to get the time it took the projectile to reach a maximum height and slow to a stop (3 seconds).
- If gravity slows objects at a rate of 10 m/s per second and it took the projectiles 3 seconds to slow to a stop, it must have started at 30 m/s!
- Now assign an angle, say 60°. The initial velocity stays the same, so we can use trigonometry to find the x & y components.
Vy = 30 m/s (sin 60°) = 26 m/s vertical velocity
Vx = 30 m/s (cos 60°) = 15 m/s horizontal velocity
- If the projectile starts at 26 m/s in the "y" direction and gravity slows velocity by 10 m/s each second, it will take 2.6 seconds to fall to the ground, totaling 5.2 seconds in the air.
- Since the rocket travel in the air for 5.2 seconds at 15 m/s, it will go 78 meters before hitting the ground (5.2 x 15 =78).
