All comets have tails when their proximity to the sun is such that the icy debris in the comet is warmed enough to melt and fall away from the comet.
earth's gravity
The path of a comet around the sun would depend on its mass, speed, and trajectory. It a comet enters the sun's gravitational field at the correct trajectory and speed, it would fall into a roughly circular orbit.
A comet has a long tail (hence the name comet meaning long-haired star) while a meteor is only a beam of light.
No, a weed plant would not die if its leaves fall off. The plant may undergo some stress, but it can recover and produce new leaves as long as its roots are healthy and the growing conditions are favorable.
we are not sure.

earth's gravity
Comets, while visible in the sky, do not normally fall to Earth. Meteors do fall towards Earth very quickly.
comet moves slowly and appears in the sky for a longer time. meteor moves swifty and seems to fall on the ground.
Pieces of comet fall several times a year, in each meteor shower.
Sometimes they do; that's what a "meteor shower" is. The point is that all of the rocks and dust given off by a comet, and the head of the comet too, travel the way gravity and the light pressure of the Sun force them to. The head of the comet is freely falling towards the Sun. (if a comet gets close enough to a planet, the gravity of the planet becomes significant, and sometimes the comet will collide with the planet; look at Shoemaker-Levy 9, which hit Jupiter in 1994.) As the heat of the Sun begins to melt the ices of the comet, gas and dust escape from the comet. Because the gas molecules and dust particles are very light, the pressure of the Sun's light pushes them away from the comet; this forms the "tail" of the comet. Over the course of thousands of orbits, the gas and dust spreads out to fill in much of the orbit of the comet. Where the Earth's orbit intersects the comet's orbit, we see annual meteor showers.

The "vomit comet" is a nickname for aircraft used to simulate microgravity, typically by flying in parabolic arcs. During these flights, the aircraft experiences free fall, creating a sensation of weightlessness for passengers and objects inside. The relationship with mass comes into play as the effects of gravity on mass are temporarily negated during the free-fall segments, allowing participants to experience the conditions of reduced gravitational force. This phenomenon is crucial for training astronauts and conducting scientific experiments in a microgravity environment.

Sleet is heavier and worst then hail. Yes, and No! They are both frozen rain and they are both unpleasant. The main differences are the times of year they fall and the weather conditions that produce them.
