Pro Tip 1/3Physical Movement
Used to discuss the physical force that makes something move.
Without proper propulsion, the boat drifted aimlessly.
Pro Tip 2/3Machinery Context
Refers to parts of machinery involved in making objects move.

They have the most impressive nervous system in the entire invertebrate world. They have about a half a billion neurons that are distributed throughout their body, such that two-thirds of the neurons are actually in its legs. Now mix this in with camouflaging cells, jet propulsion and a razor-sharp beak, and you have all the makings of a formidable predator.

but we leave the second stage in this highly elliptical orbit. And at the perigee of the orbit, or the lowest point, it dips into the Earth's atmosphere and basically burns back up. So now we're left with this little kick stage, that white thing on the corner of the screen. It's got its own propulsion system, and we use it to raise and trim the orbit

That set me on the road to examining biomechanics. So here are the new rules of swimming, if any of you are afraid of swimming, or not good at it. The first is, forget about kicking. Very counterintuitive. So it turns out that propulsion isn't really the problem. Kicking harder doesn't solve the problem

to attenuate the shock of the limb hitting the ground. Then at mid-stance, the bionic limb outputs high torques and powers to lift the person into the walking stride, comparable to how muscles work in the calf region. This bionic propulsion is very important clinically to patients.

Shervin Pishevar
Iranian Businessman
We're very focused on building the hyperloop. And the hyperloop is exactly something we've described as an actual tube with levitation propulsion and a vacuum that essentially vents around sky inside the tube flying at 200,000 feet. That, to us, is the hyperloop, and we're the only company building that.
Quote examples
Martin Rees
British Scientist
It would be sad if the expertise built up during the 40 years of the U.S. and Russian manned programmes were allowed to dissipate. But abandoning the shuttle, and committing to new launch vehicles and propulsion systems, is actually a prerequisite for a vibrant manned programme.
Quote examples
Gene Cernan
American Astronaut
Chemical propulsion is obsolete to go anywhere other than the moon. Three days - that's acceptable. But for Mars, we need propulsion technologies to get us there in, say, 60 days - then spend whatever length of time we want to spend and return when we want to come home.

Michael Finkel
American Journalist
In my writing, I try to combine all my favorite elements of journalism - accuracy, real characters that exist on this planet - with all my favorite elements of literature: a sense of flow, of propulsion, of wanting to read every sentence.

American Businessman
If you stop and think about it, the form of propulsion used today hasn't changed in over a thousand years... since the invention of fireworks by the Chinese.

Edgar Mitchell
American Astronaut
We do need different types of propulsion to get to Mars. I wrote one of the first Ph.D. theses on that in the 1960s.

The railroad originally was as completely dissociated from steam propulsion as was the ship.
