Fields and Forces

Question 1

what is gravitaional attraction dependent on

Answer 1

the two objects masses and the distance between them

Question 2

what is a field

Answer 2

an area of influence, hwo two objects not in contact can exert a force on to eachother

Question 3

why does it seem like astronauts are floating space

Answer 3

they are not actually floating
they are in freefall
gravity is causing all objects to fall at the same rate, resulting in appearance of weightlessness, or microgravitys

Question 4

important aspects of satellite motion

Answer 4

they are projectiles, only force acting upon them is gravity
constantly falling, not towards earth but around it
same characteristics as circular motion

orbital speed will depend on the strength of the gravitational field at the orbital radius

Question 5

what is electric force

Answer 5

the attractive or repulsive interaction between any two objects with a charge
theb force between two charged objects is directly proportional to their charge and inversely proportional to their distance

Question 6

what are vectors or scalar quantities for forces and fields

Answer 6

fields are vectors and forces are scalar
