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
