Why is that?<\/p><p>Next Question\u2026. What can we do to AIM our catapults? What if we want to vary the distance (or range) that our projectiles travel? What do we have to work with?<\/p><p>\u00a0<\/p><p>Catapults convert POTENTIAL ENERGY stored in our RUBBER BAND into KINETIC ENERGY\u2026 of the moving lever arm and our PROJECTILE.<\/p><p>The POTENTIAL ENERGY stored is a function of the spring constant of our RUBBER BAND, and how much we STRETCH it.<\/p><p>We convert that potential energy (stored energy) into KINETIC ENERGY (moving energy).<\/p><p>The general equation for KINETIC ENERGY is 1\/2 * mass * velocity * velocity.<\/p><p>Our system is a little more complicated than our egg drop system\u2026 we\u2019re also using some of that energy to move the lever arm as well as the projectile. Don\u2019t worry about that. It\u2019s a constant for our system. You\u2019ll still see a relationship between the weight or mass of our projectile and the velocity or distance that it travels.<\/p><p>TRICK QUESTION\u2026 We\u2019re measuring DISTANCE and WEIGHT.<\/p><p>But our relationship for Kinetic Energy is a function of mass (=weight) and VELOCITY.<\/p><p>Is there a relationship between VELOCITY and DISTANCE?<\/p><p>DISTANCE = VELOCITY * TIME\u2026. and actually it\u2019s the horizontal component of velocity that matters here.<\/p><p>So the hang time that the projectile stays in the air determines how long it has to travel. Got it? Make sense?<\/p><p>SO\u2026 Advanced question\u2026. What can we do to alter our hang time?<\/p><p>Well, we can change our launch angle. A more vertical launch angle will give us more hang time, but at the expense of horizontal velocity. Which is more important for our catapults? Test and find out!<\/p><p>What if we still want more RANGE? Is there a way to jump the curve and get even more distance?<\/p><p>Well\u2026 can you think of a way to put more POTENTIAL energy into the system?<\/p><p>The POTENTIAL ENERGY is a function of the spring constant of our rubber band, and the amount of STRETCH or elongation. We can increase the potential energy stored by stretching our rubber band more (changing the launch angle), or by increasing the spring constant.<\/p><p>Any ideas how to do that?<\/p><p>If you guessed adding a second rubber band, or using a stiffer rubber band, you\u2019re right!<\/p><p>Check out the first video to see some tests using 1 rubber band and firing the catapult at a target, then using 2 rubber bands.<\/p><p>Can you think of other games you can play with your catapult?<\/p><p>\u00a0<\/p><p>PLEASE\u2026. Do not AIM your catapult at another person or animal. It can make a fun game to let your cat or dog CHASE a ball that you shoot with your catapult.\u00a0<\/p><p>SHARE a picture or video of your catapult by posting in this thread!<\/p><p>I&#8217;ll be
