Respuesta :
Yes, Kinetic Energy is a scalar quantity because the direction is not needed. A scalar quantity is one dimensional measurement.
Explanation:
- Kinetic Energy is a scalar quantity that means it has only a magnitude and no direction.
- Energy has a size but no direction; two objects can have the same kinetic energy but they travel in opposite directions.
- The formula of Kinetic Energy is
- K.E = [tex]\frac{1}{2} mv^{2}[/tex]
- Mass is a scalar quantity and velocity is a vector quantity.
- squaring velocity will make vector to scalar quantity.
The kinetic energy is a scalar quantity as it requires only magnitude for description.
Explanation:
Scalar quantity refers to the quantity that has a single dimension. It is not dependent on the direction and has magnitude only, like Temperature and Mass.
Kinetic energy is possessed when the object is set in motion. Any object whether it is moving straight or spinning possess kinetic energy. It depends on two variables, namely, mass and velocity or speed of the object.
Kinetic Energy: K.E. = [tex]\frac{1}{2}[/tex] × m × v²
The metric unit to measure Kinetic energy is Joule (J).
