gravity & tides
the moon's gravity is what of earth's gravity
1/6
if you weigh 100 newtons on earth how much would you weigh on the moon
16.667 newtons
at the beach high tides occur at 8 a.m so when will the next tide most likely occur
8 p.m
what is gravity
A type of force.
tidal energy
Energy that comes from the movement of water driven by the gravitational pull of the Moon.
High tides occur
On the side of the earth facing the moon, and also the opposite side
gravity acts on
all matter in the universe
according to albert einstein gravity
bends space and time
the moon's gravity affects
both the soil parts of the earth and the oceans
the rise and fall of the oceans water level
ceaseless
what causes tides
gravitational pull of the moon, sun, and earth
Why and how does gravity happen
gravity holds planets in orbit around the sun and what keeps the moon in orbit around Earth.
neap tides produce
high tides are lower, low tides are higher
spring tides produce
higher high tides and lower low tides
What position must the Moon be in to produce a solar eclipse
in a direct line between Earth and the Sun.
what effect does the moon's gravity have on earth
it causes the tides
what are the two factors gravity depends on
mass and distance
ceaseless
never ending
what moon phase does the spring tide occur
new moon and full moon
How is the umbra different from the penumbra
one's about the part of the shadow where the eclipse will be seen as full. The other is about the area of the shadow where an eclipse will be seen as partial
tidal energy also causes very little
pollution
during neap tides the moon,sun, and Earth form a
right angle
during spring tides the moon, sun, and Earth form a
straight line
what affects tides the most
the Moon
why do the tides even out during a neap tide
the Suns effect on tides reduces the Moon's effect
mass
the amount of matter in an object
how does the distance between two objects affect the force of gravity
the closer the two objects are the more gravitational force they have.
Why is the earth's gravity stronger than the moon's gravity
the earth is more massive than the moon
how does mass on an object affect gravity
the greater the mass the more gravitational force
If the sun is bigger than the moon, why does the moon have a greater effect on tides
the moon is much closer than the sun
what might happen if the moon was half as large as it is now
the ocean level will rise and fall less dramatically
waight
the pull of gravity on the mass of an object
why are high tides higher and low tides lower during a spring tide
the sun and moons effects combine creating a stronger force
what might happen to the earth if it's orbit moved farther away from the sun
the sun's gravitational pull on earth would decrease
how does the sun's gravity compare to the earth's gravity
the sun's gravity is stronger
what is the force that causes all planetary movement in the solar system
the sun's gravity is what causes the planets to orbit in our solar system
what theory did albert einstein introduce to challenge newton's idea
theory of relativity
what might happen on the beach as the tides goes out
there will be more sand
the moon's gravity causes what thing that has to do with tides
tidal bulges
the daily rise and fall of sea level
tide
what would you expect to happen to the number of high tides in any given area if the rate of earth's rotation doubles
tides would occur about twice
How many times a day does the water rise and fall to produce tides
twice
