What does it mean to say momentum is directly proportional to mass and velocity?
Being proportional means that if you change one by a given factor, the other will change by that factor as well. Being proprtional to both means it is proportional to their product, i.e. momentum equals mass times velocity, p = mv.
What does it mean to say mass and weight are proportional to each other?
It means that although they are not equal, there is a correlation between them, e.g., mass directly affects weight. If an object has more mass, it will weigh more.
What does it mean to say that the object's acceleration is inversely proportional to the mass?
the bigger something is, the longer it takes to get it rolling at ______ speed.
How does surface area and force affect pressure?
Pressure is force per area, so P = F/A where pressure is P, force is F and A is area. So Pressure is directly proportional to the force exerted on a surface. So increasing a force by a factor of 2, say, increases the pressure on the surface by 2 also.
What did Newton say about how the distance between two bodies affects gravity?
Newton said that the gravitational attraction between two objects is directly proportional to the product of the two masses and inversely proportional to distance squared. Gravitational attraction between masses A and B = constant x mass A x mass B / distance2
What is the symbols of inversely proportional and directly proportional?
The greek letter "alpha" (α) for both. If x is directly proportional to y, you could say x α y. For inversely proportional, you would say something like x α 1/y, or x α y^-1, as in, directly proportional to the inverse.
Which variable is inversely proportional to the resistance?
If you have a conductor ... say, a copper wire ... and you keep its diameter and temperatureconstant, then yes, its resistance will be directly proportional to its length.
Does y varies directly with x if y54 when x 6?
y=54 if x=6 so we can write y=9(x) so y=k(x) clearly y is directly proportional to x.
What does it mean to say momentum is directly proportional to mass and velocity?

It means that although they are not equal, there is a correlation between them, e.g., mass directly affects weight. If an object has more mass, it will weigh more.
What does directly porportional mean?
It is a special kind of linear function wear the line on a graph goes straight through the origin. If x is directly proportional to y, then it means that for a value of x, y = cx, where c is some constant. For example, if a slice of pizza costs a fixed cost (say 1 dollar), then the cost of your pizza meal is directly proportional to the number of slices you order. (Cost = 1 times number of slices.)
What does it mean when you say the x- variable and y-variable are inversely proportional?
X = YY = X=======these are directly proportionalX = 1/YY = 1/X========these are inversely proportionalTry a few inserted numbers and graph these to see, visually, the difference.
How does the force in which you kick the soccer ball affect how far it travels?
Hit it harder, it goes further. That is to say that force is directly proportional to the distance travelled.
What is the relationship between current and conductor crosssectional area?
Specific resistivity is directly proportional to area of cross section of the conductor and specific conductivity is the inverse of specific resistivity. So we can say , Specific conductivity is directly proportional to area of cross section of the conductor.
What is a directly proportional equation?
To say that an equation is directly proportional is somewhat incorrect. What we say instead is that a variable on one side of the equation (in other words, on one side of the equals sign) is directly proportional to another variable on the other side.What this means is that if when one variable increases (gets bigger), the other one does, too, then these variables are directly proportional to each other.For example, take the equation for velocity.v = d/tHere, v is velocity, d is distance, and tis time. Lets try a few numbers.v = 100 miles/2 hours = 50mi/hr.v = 200 miles/2 hours = 100mi/hr.v = 400 miles/2 hours = 200mi/hr.What you may notice here is that as the value of d (the number of miles being traveled), gets bigger, so does the value of v (velocity, or speed, in miles/hour). This is because, in this equation, velocity is directly proportional to distance.
What does it mean to say that the object's acceleration is inversely proportional to the mass?
the bigger something is, the longer it takes to get it rolling at ______ speed.
The number of times a dog barks is dependent on the number of passing cars How many cars have passed when a dog barks 34 times?
"Dependent" does not say whether the relationship is directly proportional or indirectly proportional; or some other function of the number of cars.
