A direct relationship between two parts of an equation means:
One part doesn't beat around the bush when it wants to address something sensitive between the two
One part tells the other where to stand, how to use their body language, and deliver lines for a scene to elicit the proper reaction from audiences
If one increases in value, the other decreases in value
If one increases in value, the other increases in value
A inversely proportional relationship between two parts of an equation means:
One part grabs the top part of a halfpipe and stands upside down on a skateboard or snowboard
One part is quiet, kinda keeps to themselves, isn't really outgoing to socialize with others, but is okay with it all and is more comfortable in smaller group settings.
If one increases in value, the other decreases in value
If one increases in value, the other increases in value
The sun is the anchor point of our solar system because of
the gas Hydrogen
its small density
its huge mass
its location
How are mass and weight different?
Mass is the amount of matter in an object; Weight is the amount of gravitational force acting on the object
Mass is the amount of gravitational force acting on an object; Weight is the amount of matter in an object
Mass is a thing;Weight is a place
Mass is an animal;weight is a human
How does Fg(2 on 1) compared with Fg (1 on 2)?
They have the same magnitudes but opposite directions
They have the same directions but opposite magnitudes
They have the same magnitudes and directions
They have opposite magnitudes and directions
Here mass 1 is clearly bigger than mass 2. Compare their forces.
The magnitude of the force on mass 1 is bigger than on mass 2
The magnitude of the force on mass 2 is bigger than on mass 1
The magnitude of the force on both mass 1 and mass 2 are the same
The masses of the objects must be known to compare their forces of attraction.
If the mass of the Earth is labeled mE, the mass of object A is m, and the radius of the Earth is R, then what is the gravitational force between them?
RGmEm
R2GmEm
RG(mE+m)
2RG(mE+m)
Two satellites of equal mass are in circular orbit around a planet. Satellite b is twice as far out. Which feels a stronger gravitational force?
Satellite a
Satellite b
Both the same
Depends on the mass of the satellites

a
b
c
d
The space shuttle is orbiting the Earth clockwise. Which vector shows the direction of the shuttle's tangential velocity?
a
b
c
d
Which diagram best shows the gravitational interaction between Earth and a satellite?
You are talking to your friend who is sitting 1.5 m in front of you. If your mass is 60kg and your friend's mass is 50 kg, what is the gravitational force between you and your friend?
A 6.9 x 10-8 N
B 8.9 x 10-8 N
C 9.5 x 10-8 N
D 1.3 x 10-7 N
When do gravitational forces exist between two objects?
They only exist between objects that are moving in a circle.
They are always present between any two objects.
Gravitational forces only act on objects falling on Earth.
They only exist for objects in space.
A rocket moves away from the surface of Earth. As the distance r from the center of the planet increases, what happens to the force of gravity on the rocket?
The force doesn’t change
The force increases directly proportional to 𝑟2
The force decreases inversely proportional to 1/𝑟2
The force becomes zero after the rocket loses the contact with Earth
