Fish use their fins and tail to propel forward. Also, the streamlined shape of their bodies overcome water resistance, allowing them to move easier and quicker.
In a wave, energy is transferred through the medium by the particles vibrating back and forth in place, while the wave itself moves forward. The particles themselves do not move forward with the wave but rather oscillate about their equilibrium positions as the wave passes through.
'Forth' is a word used to describe movement. It can be denoted as moving forward from a specific place or moving forward in time. It can also be described as an outward motion. Moving 'forth' could be considered moving 'out of concealment' (as in moving forth or bringing forth).A forth could also be an incorrect spelling of 'a fourth', which is one out of four. In ratio form, 1:4. It is considered a rational, 1/4. The term 'a fourth' is a grammatical way to describe one-fourth of something or other. I.E: "I only see you do your work a fourth of the time." or "What is a fourth of 75?"
The medium moves perpendicular to the direction of the wave. In a transverse wave, the particles of the medium move up and down or side to side, while the wave itself moves forward. In a longitudinal wave, the particles move back and forth in the same direction as the wave propagation.
A longitudinal wave is caused by the back and forth movement or vibration of particles. This type of wave involves the displacement of particles parallel to the direction of the wave itself.
To waver back and forward in decision making.
forth, on, ahead, onwards
forth, like forward.
One homonym for "fourth" is "forth," which means forward or onward in direction.
Fourth is like the number 4. Forth is to go forward.
You can tell if a horse is mad if their ears are pinned to their head, their tail is swishing harshly back and forth, and sometimes the whites of the horses eyes are showing.
forward, out, away, ahead, onward
In a forward direction.
Con rods are used not ony in car engines, but in just about all piston engines. They're needed to turn the reciprocating(back-forth) motion of the piston into the rotary motion of the crankshaft. That rotation is then - via the gearbox, prop shaft etc what propels the car forward.
To rush forward. Every oneward and such....
In some words it means "forward" or "forth."
Back and forth
In a wave, energy is transferred through the medium by the particles vibrating back and forth in place, while the wave itself moves forward. The particles themselves do not move forward with the wave but rather oscillate about their equilibrium positions as the wave passes through.
