Hermann von Helmholtz Quotes

An object in motion tends to remain in motion along a straight line unless acted upon by an outside force.

Every body continues in its state of rest or uniform motion in a straight line, except insofar as it doesn't.

Though we may never be able to comprehend human life, we know certainly that it is a movement, of whatever nature it be. The existence of movement unavoidably implies a body which is being moved and a force which is moving it. Hence, wherever there is life, there is a mass moved by a force. All mass possesses inertia; all force tends to persist.

For every action there is an equal and opposite reaction.

A point of rest alone explains motion.

To every action there is always opposed an equal reaction.

Acceleration is finite, I think according to some laws of physics.

For relaxation, I like to figure skate. Being on the ice and spinning and jumping, I feel very close to nature. In particular, I feel very close to Newton's laws of motion. On the ice, you can experience Newton's laws of motion in their purest, most elegant form.

Action and reaction are equal and opposite.

If you move something 10 pounds through space and then stop suddenly, there's a little overshoot. When you transfer weight from one leg to another, there's a certain way that it happens.

Playgrounds are essentially machines to induce Newtonian physics on our own bodies.

Resistance is usually ascribed to bodies at rest, and impulse to those in motion, but motion and rest, as commonly conceived, are only relatively distinguished; nor are those bodies always truly at rest, which commonly are taken to be so.

It is indeed a law of politics as well as of physics, that a body in action must overcome a body at rest.

Momentum,' She repeats. 'You can't just stand there if you want something to fly. You have to run.

Ax: 100 Every thing doth naturally persevere in yt state in wch it is unlesse it bee interrupted by some externall cause, hence... [a] body once moved will always keepe ye same celerity, quantity & determination of its motion.

Every body persists in a state of rest or of uniform motion in a straight line, unless it is compelled to change that state by forces having impact upon it.

Any schoolboy could see that man as a force must be measured by motion, from a fixed point.

If your position is everywhere, your momentum is zero.

The natural law of inertia: Matter will remain at rest or continue in uniform motion in the same straight line unless acted upon by some external force.

Not all speed is movement.

I figured it out eventually," she says. She's sitting on the edge of the gurney again; her features slowly materialize as my vision clears. "It's momentum." "What?" I whisper. The feeling returning to my lips, spreading out to my fingertips and toes. "Momentum," she repeats. "You can't just stand there if you want something to fly. You have to run.

No lens is quick enough to track the movement of the human body. The molecules are always moving.

I know all we're doing is travelling without moving. Speed freak faster than a speedin' bullet, slow down. If I don't, I might just lose it, locked up. You've got me honey, locked up under heavy brakin', yeah. You know I've got to hang on, drive too fast, I might be last.

If the oarsmen of a fast-moving ship suddenly cease to row, the suspension of the driving force of the oars doesn't prevent the vessel from continuing to move on its course. And with a speech it is much the same. After he has finished reciting the document, the speaker will still be able to maintain the same tone without a break, borrowing its momentum and impulse from the passage he has just read out.

Impressed force is the action exerted on a body to change its state either of resting or of moving uniformly straight forward.
