The Physics of Star Trek – Warp Speed “Engage.” One simple command that triggers an entire series of complex reactions deep in the core and within the warp nacelles of the Starship Enterprise. Engage implied not only a command to fly off into the unknown reaches of space‚ but also a revolution of thinking that combined fundamental physics with the innovative ideas of the future. Warp technology‚ as envisioned by the writers of Star Trek‚ can be linked to today’s world of physics: Newton’s third

the same. This means that the velocity is not constant. 4) Now move the ball at a slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. While moving the ball at a slow constant speed across the screen‚ I noticed that the velocity is constant. This happened because there was no acceleration. It was just a very constant slow speed. 5) What happens to the vectors when you jerk the ball rapidly back and forth across the screen? Explain

factors make a hot air balloon or a helium balloon float Student Instructions: 1. Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more that the weight. Buoyancy occurs because the hot air has a lower density than the cooler outside air. This lower density air weighs less than the air it replaces and that difference is the buoyancy. 2. What makes balloons float when they are full of air but not float when

The Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would

ABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment‚ one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2‚ which is consistent with the accepted value of 9.8m/s^2. In the
