How do I get the cup of the catapult to interact more accurately and completely with the ball? I increased the physics fps to 100 to see what would happen, and that didn't fix it. The History of the Catapult This classic STEM activity was first invented in 400 BCE Invented by The Greek Dionysius the Elder of Syracuse. On the next rotation, it does the same thing. Also it works on energy storage mechanisms (nothing but the stored potential energy and energy in motion kinetic energy) says that a catapult works on physics. I hear it over and over from teachers and parents alike, nothing has inspired the kids to learn physics and engineering- even math, more than the catapult. When I spin the arm, the ball almost completely passes through the floor, barely affected by it. A catapult actually works on the three main terms of physics i.e. cube(this is the arm connecting the cup to the center).kinematic rigidbody with interpolate on.rigidbody with interpolate on, frozen every way except z rotation.When they pull the metal 'arm' back further, thus applying a greater force to the cotton ball, it causes the cotton ball to travel faster and farther. They learn how Newton's second law of motion works by seeing directly that F ma. Weird things started to happen when I increased the z magnitude of the torque vector(to 5). Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. This version rotated and pushed the ball along with it,but it didn't throw it very much. _rigidbody.AddTorque(new Vector3(0,0,1))

Here's the code on arm rotation parent(which I made so that the arm rotated like a catapult arm) if (Input.GetKey(Ke圜ode.Space)) It worked, so in my test project I put some shapes together to roughly approximate my catapult to see if it could throw something. Catapult is a device used to throw an object over a distance. On my last question, someone suggested starting with something simpler (which I apologize for not doing earlier). If you keep on adding more rubber bands in the hope of an ever-increasing force, you will find that the strength of your frame becomes the limiting factor.This should be my final question regarding getting a catapult to throw something in unity. But the rubber band will then exert a stronger force on the catapult arm and the ball, causing it to accelerate more, shooting the ball further. Hooke’s Law tells us that if we increase the spring constant (by using a thicker rubber band or adding more thinner rubber bands), we will have to use a stronger force to stretch the rubber band when we pull back the catapult. To be a real catapult the machine generally has to be too.

A catapult can be as small as a rubber band slingshot used to skim rocks across a pond or as large as the 90-m (300-ft) long steam units used to launch airplanes from aircraft carriers. The force that the stretched elastic band exerts on the wooden catapult arm causes it to accelerate and that accelerates the ball too. Catapult is a device used to throw an object over a distance. The main types of catapults used were the trebuchet, mangonel.

Some of it ends up in the thermal store of the surroundings. The catapult has proven to be a very effective weapon during ancient times. But not all of the energy from the rubber band’s elastic store has been transferred to the kinetic store of the ball. Experimental Physics, >, Instruments, >, Simple Machines, v.

Īt the end of the process, the kinetic store of the ball is full and the elastic store of the rubber band is empty. At the start, the elastic store of the rubber band is full and the kinetic stores of the catapult arm and the ball are empty.
