Is acceleration directly proportional to mass or is it inversly proportional to mass?
Depends what u mean by that. If it is free falling it would obviously be accelerating at 9.8m/s^2. If there is an incline then it depends. I believe acceleration is directly proportional to velocity though.
Are the mass and volume of a given substance directly or inversely proportional?
Generally speaking when the mass of a substance increases, so does its volume. And vice versa. Therefore mass and volume are directly proportional. If they were inversely proportional one cup of water would weigh more than 2 cups of water.
How is the term 'energy' defined in physics?
Energy is the capacity of a body to do work. Mass and energy are directly proportional according to Einstein's famous equation, E=mc^2.
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.
Two examples of flammable things?
1) gasoline 2) paper
How is amplitued related to loudness?
(amplitude)2 is directly proportional to loudness.

What happens to an objects kinetic energy as its mass increases?
kinetic energy, K.E = 1/2 mv^2 that is, it is directly proportional to mass, assuming velocity to be constant and is directly proportional to square of velocity assuming mass to be constant.
What does proportional change?
When 2 things increase or decrease by the same proportion
What are some examples of direct proportion?
x is directly proportional to y if when x is increased (or decreased) by a relative amount then the same relative change occurs in y. So, if x is doubled, for example, then y is also doubled. Examples are: 1. Weight is equal to mass * gravity. Here mass and weight are directly proportional (when measured in the same gravitational field). For example, if we double the mass then the weight is also doubled. 2. In electronics there is a law called Ohm's Law which states: voltage = current * resistance (V = IR). Here the voltage is directly proportional to both current and resistance. For example, if we halve either the current or resistance then the voltage is also halved. There are lots of other examples you could find.
What 2 variables effect gravity?
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
What is a proportional relationship between 2 quantities?
A [directly] proportional relationship between two variables, X and Y implies thatY = cX where c is the constant of proportionality.

What is the definition for non-proportional?
Here is a quick definition: un-proportional is where two things cannot ever be equal or similar, for example 2 is proportional to 4, because if 2 is doubled it becomes 4, but 3 is not proportional to 5 because they can never be equal. I hope this helped
If y is proportional to the square of x fully explain what happens when x is doubled?
Example with numbers: Y = X2 Y = (2)2 Y = 4 ==== So if Y is ( directly ) proportional to X2 when X is doubled Y is increased four times.
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.
