Astro 7N Unit 1
In line with newton's second regulation of motion, if the net force acting on the object will
increase while the mass of the item remains regular, what occurs to the acceleration?
Acceleration will increase
if the earth have been moved to 1/2 its current distance from the solar, how might the pressure
of gravity by way of the sun on earth alternate?
It'd be 4 times more potent
what did newton's regulation of time-honored gravitation tell us about how gravity works?
The pressure of gravity from the solar might be stronger on an object with greater mass
the earth radius is ready 6400 km. In case you have been in orbit inside the space station 150
km above the ground, the force of gravity you feel from earth could be
slightly weaker than while you are status in the world
if you had been to take a seat at the floor, there might be a pressure due to gravity pulling you
closer to the earth. Which of the following is genuine in keeping with newton's 3rd law?
You are pushing the earth far from yourself with the same pressure
what might happen to the earth if the solar's gravity in some way turned off right now?
It'd retain to move in a line inside the identical course it changed into moving while the gravity
turned off
remember a planet whose rotation axis isn't tilted with recognize to its orbital plan. What are the
seasons like on the earth?
There are not any seasons
, if the earth circled on its axis greater slowly than it does now
the days might be longer
if earth had its orbit modified so that at all factors alongside its orbit it had been always the
identical distance from the sun (circular orbit), how might this affect the seasons in the world?
They might be the same as they are now
a new planet orbits its star quicker than the earth orbits the sun and it rotates greater slowly
than the earth rotate. Which of the subsequent is actual?
The brand new planet has a shorter year than earth and an extended day than earth
what time of yr is it darkish all day (and night time) at the south pole of earth?
June
why isn't there an eclipse each month in the world
the moon's orbit round earth is without a doubt tipped approximately 5 tiers to earth's orbit
across the sun so the moon isn't inside the right aircraft for an eclipse to occur
what's the inclination of mars?
About 1 degree
how regularly does mar's moon, phobos, eclipse?
Every orbit
how lengthy is phobos orbit around mars?
About 8 hours
