## What is directly proportional to mass?

The force, acting on a small object with small mass by a nearby large extended mass due to gravity, is directly proportional to the object’s mass; the constant of proportionality between the force and the mass is known as gravitational acceleration.

How is mass directly proportional to volume?

We can say that the volume of the object is directly proportional to its mass. As the volume increases the mass of the object increases in direct proportion. The gradient of the graph equals the density of the material.

### How mass is directly proportional to radius?

Radius of nucleus is directly proportional to the cube root of mass number. Density of all the nuclei is same. Radius of nucleus is directly proportional to the cube root of mass number.

How energy is directly proportional to mass?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

#### What is directly proportional and inversely proportional?

When two quantities X and Y increase together or decrease together, they are said to be directly proportional or they are in direct proportion with each other. When two quantities X and Y are inversely proportional to each other, we say that “X is inversely proportional to Y” or “Y is inversely proportional to X”.

Are mass and weight directly proportional?

On Earth, your weight is directly proportional to your mass (always \% \%), but on the Moon, since the acceleration due to gravity is lower, while weight is still directly proportional to mass, the constant of proportionality is lower (so we get about ).

## Are mass and density directly proportional?

Density is directly proportional to mass (inversely proportional to volume) but only in the circumstances where the volume remains the same.

Is mass inversely proportional to radius?

I learned that charge to mass ratio of the particles is inversely proportional to the radius of the path. Thus, a particle following a circular path with a large radius means that charge to mass ratio of that particle is smaller.

### What is the relation between radius and mass number?

The nuclear radius R is related to the mass number A as follows: R=Ro A1/3,where Ro =constant=(1.2 to 1.7) x 10 -15Thus nuclear radius varies as A1/3. While the atomic no increases the electrons in the atom increases and no of shells increases so the size of the atom increases.

Is mass inversely proportional to energy?

That equation actually indicates the opposite: energy is proportional to mass, and a heavier particle has more energy.

#### How is Ke inversely proportional to mass?

Moment of inertia is proportional to the mass of the object you’re pivoting, and the hardship you’d feel is the energy needed. So mass is proportional to moment of inertia and thus both proportional to kinetic energy of the pivoted object.
