This is a simulator that uses Newtons laws of motion to determine the motion of a rocket! Adjust the amount of fuel in your rocket by using the slider. Click the red button to launch! Click on the "Change Rocket" button to make other changes to your rocket. You can change the exhaust velocity (how fast the gas comes out the back), the throttle (how much gas we push out the back in one second), and the mass of the ship (not counting the mass of the fuel).
