Rube Goldberg Device Prezi
Transcript of Rube Goldberg Device Prezi
D=M/V The more acceleration is exerted on an object, the more force it has, the more mass the object has, the less force it has The rate of change of an objects position S=D/T Every action has an equal and opposite reaction. Elastic Forces The forces that allow objects to resist being changed D = density M= mass V= volume The force that resists stretching To calculate the average speed the equation is
Total distance/total time = average speed
50meter/25seconds= 2 meters per second per second Position is the placement of
an object in relation to another object The force that pushes matter in an object closer together so that the object has the same amount of mass, but a larger volume Newton's Laws The force of attraction that objects with mass have towards each other. F ≈ 9.8*mass Remember you can measure force by measuring F=ma Is the force that resists motion weight of displaced water is about 125 milliliters The volume of the cork is ≈ 15.6 cm cubed and the mass is ≈ 4.7 grams S=speed D=distance T=time 56 cm /2.19 s = 25.7 centimeters/second we found that the dominoes in our device travel a distance of 56cm in 2.19 seconds So... The boat in our device travels at a speed of ≈ 38cm per 4.5 seconds (or 8.44 cm per second) due West the mass of the boat is 36.9 grams formula for acceleration : Final v - Initial v / Time Time: .9 seconds Inital v =0 Final V: ≈ 11.7 ft per second v = velocity 4.7 / 15.6 ≈ .3 grams per cubic centimeter A force or Forces that
causes or changes the motion of an
object by touching it.
