100
What is the definition of gravity?
a force of attraction
100
what is the equation for the gravitational force of attraction?
f= m*m/ d2
100
What does "net force" mean?
the overall/total force (magnitude and direction)
100
Can an object exert a force on something without touching it? If so, give an example (think back to what we talked about in class)
yes, gravity
100
what is the displacement if you run a 400 meter dash around a track? what is the distance?
0
400
200
what is the gravitational force dependent on? (2 things)
mass
distance
200
if the mass of one object doubles, what happens to the force of attraction between the two objects?
it doubles
200
what is going on in this picture? what is the net force?
constant speed, 0
200
What are the two different kinds of outside forces?
contact and non-contact
200
Anyae is walking through the halls and drops her flamin hot cheetos all over the floor. What does the FBD look like when the cheetos are falling?
air drag up (short arrow)
gravity down (long arrow)
300
Gravity is responsible for orbits, true or false? Give an example
true, the earth orbiting the sun
300
if the distance between the two objects doubles, what happens to the force of attraction?
decreases by *4
300
When is the net force 0? when the forces are...
balanced
300
What has a greater impact on the force of attraction? distance or mass? why?
distance, squared
300
what does a straight diagonal line going up mean on a distance time graph?
constant speed
400
are mass and force of attraction directly or indirectly related?
directly
400
if you have two objects and one has a mass of 3 while the other has a mass of 4, what is the gravitational force of attraction if the distance between them is 3 meters?
12/9 or 4/3
400
If an object is stationary, are the forces balanced or unbalanced? What is the net force?
balanced, 0
400
what is the answer to A?
400
if you travel to your friends house (500 meters away) and get there in 10 minutes, what is your speed?
50 meters/min
500
are force and distance directly or indirectly related?
indirectly
500
One has a mass of 2 grams and the other has a mass of 2 grams, what is the gravitational force of attraction between the two objects if they are 7 meters a part?
4/49
500
If an object is moving at a constant speed, are the forces balanced or unbalanced? What is the net force?
balanced, 0
(think back to picture of car)
500
if the distance between two objects is cut in half (decreases by half), what will happen to the force of attraction? be specific.
it will increase by *4
500
what is the difference between weight and mass?
weight is the gravitational force
mass is the amount of matter we take up
