Gravity Flashcards
(25 cards)
Newtons interest in mechanics was rekindled with the advent of a spectacular what in 1680
Comet
Isaac Newton determined that gravity was
universal
Everything polls on everything else and a beautifully simple way that involves only what and what
Mass and distance
The universal gravitational consistent can be expressed by what equation
F = g (M1 and M2) / (D squared)
The magnitude of G is the same as the gravitational force between 21 kg masses that are 1 m part which is what numerical value in newtons
6.67 * 10^-11 N
Calculating G alone was first done by the what English physicist in 1798
Henry Cavendish
Philip Von jolly attached a spherical flask of what to abounds to also demonstrate the gravitational force between two objects
Mercury
Phenomena where in the effects of gravity from a local resource spreads uniformly throughout the surrounding space is termed as
Inverse square law
What is the weakest of all forces
Gravity
The force of gravity like any force can produce what
Acceleration
The pressing against earth is a sensation we interpret as what
Weight
Ocean tides are caused by the what in the gravitational pole between the moon and earth on opposite sides of the earth
Differences
What tides occur at the time of a new or full moon
Spring
Tides that occur when the moon is midway between new and full in either direction are what tides
Neap
Higher than average tides and lower than average low tides occur because the what what and what are aligned (3)
Sun earth and moon
Suns pull is what times that of the moon
180
The greatest title range can be found located in blank wheretitle differences sometimes exceed 15 m meters
Bay of Fundy
Earthquakes and volcanic corruption have a higher probability of occurring when earth is experience and what tide near a full or new Moon
Earth spring
Title effects in the blank produce electronic currents that alter the blank fields that surround the earth
Ionosphere/ magnetic
The what penetration is evident in subtle changes in the behaviors of living things
Cosmic ray
The What intensity inside a planet of uniform density is directional proportional to the radio distance from the center and is maximum at surface
Gravitational field
A concentration of mass resulting from gravitational collapse near which gravity is so intense that not even light can escape is termed as a what
Black hole
Interplanetary force is causing planets to wobble in their orbits is termed what
Perturbations
Tracking of the orbits of both Uranus and Neptune led to this discovery of what in 1930 at the what in Arizona
Pluto and Lowell Observatory
