With this one system,study collisions,Newton’s Laws,oscillations,Hooke’s Law,velocity,and acceleration.Hang weights over the included clamp-on pulley to accelerate carts or stretch the springs attached to the cart.Additional PAStracks can be purchased to extend the length of this track.
用這一系統,研究碰撞,牛頓定律、振盪、虎克定律、速度和加速度。通過加滑輪來使小車的速度加快或在小車上連接彈簧。另外PAS軌道可以購買延伸長度的軌道。
