Specification Brand : Dntum BulletPoint : U-Channel Magnet - 25 pack BulletPoint1 : The product is mainly composed of a spring gun, a scale plate, a pointer and a projectile .. BulletPoint2 : Environmental conditions in the test bed is flat and stable. b The laboratory has no wind ... BulletPoint3 : The gun spring has an effective range of about 8 meters, so be careful .. BulletPoint4 : This product is used for the experience of "measuring the velocity of the projectile" for students in physics class colleges. Can also be used for exercise experience to launch flat .. BulletPoint5 : It is noted that the pointer of the torque is too large (the rotation does not work) or too small (with inertia when rotating), the reed pressure in the form of "U" in the rotation the shaft of the pointer can be adjusted (corrected at the factory). ), And the force is applied when you press the trigger. Even vertical.
