Final answer:
In the list provided, electric potential and kinetic energy are scalar quantities, while torque and momentum are vector quantities.
Therefore, the correct options are: "electric potential and kinetic energy "
Step-by-step explanation:
In physics, scalars are physical quantities that are unaffected by changes to a vector space basis. Scalars are often accompanied by units of measurement, as in "10 cm".
Kinetic energy and electric potential are scalar quantities because they only require magnitude for their definition and don't involve direction.
- The kinetic energy of an object is the form of energy that it possesses due to its motion. In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is.
- Electric potential is defined as the amount of work energy needed per unit of electric charge to move the charge from a reference point to a specific point in an electric field.
Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction.
On the other hand, torque and momentum are vector quantities because they involve both magnitude and direction.
