... Chemical rockets eject their propellant at about a tenth of the velocity achieved by ion drives, but produce much greater thrust by ejecting more than a thousand kilograms per second. Suggest why ion drives may be preferable for missions extending over long distances and periods of time. ...

Electrogravitics Systems - Reports On a New Propulsion Methodology
... Thomas Edison, established the Gravity Research Foundation in 1948 at Edison's suggestion. So what would anti-gravity "look like"? Let us explore these issues: Standard physical models include four fundamental forces in Nature. They are the nuclear force, the electromagnetic force, the weak, nuclear ...

SPH4U Exam Review Questions - SRB 2013
... A 40.0 kg calf on a swing moves in a circular arc of radius 3.25 m. At the lowest position, the calf’s speed reaches 2.75 m/s. Determine the magnitude of tension in each of the two vertical support chains when the swing is at its lowest position. (i.e. the 2 chains exert equal amounts of force on th ...
