Answer to Question #188493 in Physics for Sajjad

Question

1 Which of the following is a scalar quantity? A weight B momentum C terminal velocity D kinetic energ

Answer 1

1. Weight is the force, thus, it can not be scalar.

2. Momentum by definition is mass times velocity. Since velocity is a vetctor, then the momentum can not be a scalar.

3. Terminal velocity is vector as well.

4. Any energy is a scalar, thus, the kinetic energy is the right answer.

Answer. D kinetic energy.
