What are catapults?
S
Will the mass of an object thrown by a catapult affect its distance? S The Effect of Bolt Mass vs. Depth of Penetration S Find the length of a pendulum through its period. S How Does the Period of Motion of a Pendulum Depend on Its Mass, Amplitude, or Length? R Make a model of an elevator, and an animation of how it works. S Demonstrate how an elevator works through a series of pulleys S The effect of length, mass, and arc on the frequency of a pendulum S Explores the hypothesis that stopping distance of a toy car in its ‘natural motion’ varies when it travels on different surfaces and incline plane S How much energy is needed to bring a wheeled object up a ramp? S Build a simple rocket engine you can build in your kitchen R Force, Motion & Energy Science Fair Projects Interdisciplinary Topic: Energy |

How Does the Length of the Arm of a Trebuchet Affect the Distance an Object Can Be Launched?
R
Test how different size pilot holes affect torque required to advance screws into wood. R How Does Center of Gravity Affect a Crane Design? R The Effect of Wheels on Catapult Efficiency R Maximizing the Trajectory of a Trebuchet R Measuring Human Horsepower R Build your own wind tunnel and demonstrate Bernoulli’s Principle R The More Pulleys, The More Pull R Discover the relationship between the amount of pressure put in the tank of an air cannon and the distance that the projectile flies. R Measure how much torque in newton-centimeters was required to turn a lag screw in a block of wood as the diameter of the screw, the depth of the screw, or the size of a pilot hole was changed. R Evaluate how different sling lengths and counterweight masses affect the distance a trebuchet throws a ball. R R Demonstrate Newton's Third Law of Motion by a rocket car with escaping air as the action force. R Replicate Galileo's Pendulum Experiments R R Compare modern parachute performance to that of Leonardo da Vinci’s design R Is the distance of a certain mass when launched by a catapult affected by the potential energy and angle of the catapult?

R
Is the harmonic motion of a pendulum affected by friction? R Repeat Henry Cavendish’s experiment - Build your own torsion balance R Investigate the stopping distance required by moving vehicles when a retarding force acts on them R Build and demonstrate your own Foucault pendulum R Amusing Physics: A look at physics concepts and how they apply to amusement park rides - roller coasters, swing rides, pendulum ride, free fall, bumper cars and games.
