What is the difference between scalar and vector quantities?
What is the difference between scalar and vector quantities?
- Scalar quantities are related to time, while vector quantities are related to space
- Scalar quantities have both magnitude and direction, while vector quantities have only magnitude
- Scalar quantities are constant, while vector quantities vary with time
- Scalar quantities have only magnitude, while vector quantities have both magnitude and direction (correct)
What is impulp in the context of force and motion?
What is impulp in the context of force and motion?
- A measure of rotational motion
- The resistance to motion of an object
- The product of force and time
- A misspelling of impulse (correct)
What is the statement of the conservation of linear momentum?
What is the statement of the conservation of linear momentum?
- The total linear momentum of a system changes direction over time, if no external forces act on it
- The linear momentum of a system increases with time, if external forces act on it
- The linear momentum of a system decreases with time, if internal forces act on it
- The total linear momentum of an isolated system remains constant over time, if no external forces act on it (correct)
