A Study on Student Teachers’ Misconceptions and Scientifically Acceptable Conceptions About Mass and Gravity
Type: Empirical
Data collection method: Interview
Number of subjects, range: Large — 31 or more
Grade and age of subjects: Adult — over 18 years
- Weight of a body is the same everywhere in the universe. However, mass have different values at different regions of the universe.
- There is no gravity in the space.
- The mass of a body is as much as 1/6 of it in the world because gravitational acceleration has taken different values at the space.
- There is acceleration in the gravitational mass, but not in the inertial mass
- Criterion of the inertial of a body is at the same time the gravitational mass.
-
The gravitational mass is the gravitational acceleration that is applied on a body.
-
The inertial mass is unchanged according to place where it is located, but the gravitational mass changes.
-
The gravitational mass is the force that a body applies to the earth.
-
The gravitational mass is gravity, but the inertial mass is the mass of a body while it is stationary.
-
The gravitational mass is a vector quantity, but the inertial mass is a scalar quantity.
-
Gravity is the same everywhere and has a constant value. Mass changes and depends on gravitational acceleration.
-
Gravity is the gravitational acceleration that acts on a body Mass depends on density and volume, but weight does not.
-
The gravitational force is important for gravity Mass is the specific gravity of a body.
