The Force due to Gravity Depends on Mass and Distance Flashcards
What does the weight of any object depend on?
The strength of the gravitational field it is in
What do gravitational field strength depend on?
The mass of the body creating the field
The larger the mass of the body….
The stronger it’s gravitational field
What else does gravitational field strength vary with?
Distance
The closer you get to a star or planet…
The stronger the gravitational force is
The stronger the force…
The larger the instantaneous velocity needed to balance it
The closer to a star or planet you get…
The faster you need to go to remain in orbit
For an object in a stable orbit. What happens if the speed of the object changes?
The size of its orbit must do so too
Faster moving objects will move in a…
Stable orbit with a smaller radius than slower moving ones
