PHYSICS MISCONCEPTIONS

Misconceptions are located on the left side of the tables, and references about the corresponding misconception are on the right.

STANDARD III: Students will understand the factors determining the strength of gravitational and electric forces.

Objective 1: Relate the strength of the gravitational force to the distance between two objects and the mass of the objects (i.e., Newton's law of universal gravitation).

Students believe that gravity "holds" things Driver, 1994, p. 163.
Students believe objects are pushed down rather than being pulled down by gravity. Driver, 1994, p. 77.
Students believe big means the same thing as heavy, massive means the same thing as big, and weight means the same thing as mass. Arizona, 2001; Driver, 1994, p. 78.
Students believe air and gas are weightless and have no mass. Arizona, 2001; Driver, 1994, p. 77.
Students believe the higher the altitude, the stronger the gravity until outside the atmosphere. Driver, 1994, p. 163.


STANDARD IV: Students will understand transfer and conservation of energy.

Objective 1: Determine kinetic and potential energy in a system.

Students believe potential energy is a thing that objects hold (like cereal stored in a closet). UWSP
Students believe that the only type of potential energy is gravitational. NASA
Students believe that doubling the velocity of a moving object will double its kinetic energy. NASA
Students believe stored energy is something that causes energy later. It is not energy until it has been released. NASA
Students believe objects do not have any energy if they are not moving. Arizona, 2001


Objective 2:Describe conservation of energy in terms of systems

Students believe energy is a thing that can be created and destroyed. Tomatosphere
Students believe energy is literally lost in many energy transformations. AIP
Students believe gravitational potential energy depends only upon the height of an object. AIP
Students believe conservation of energy means energy should be conserved. Arizona, 2001


Objective 3: Describe common energy transformations and the effect on availability of energy

Students believe energy can be recycled. Arizona
Students believe energy can be changed completely from one form to another with no loss of useful energy. AIP
Students believe heat is a substance and not energy. AIP
