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 =
- Mass is a scalar quantity and velocity is a vector quantity.
- squaring velocity will make vector to scalar quantity.
Answer:
Water temperatures are slow to heat up, It takes 4 times the energy to heat up water than to heat air. Water also "feels" colder because water is a more efficent medium than air to cool our body down.
Re word it tho
Hope this helps!!
Melting ice is not a chemical reaction, but is a physical change. There is no chemical reaction involved during the melting process, and it is still the same molecular substance.
<span>Heat in a substance is still an example of heat
or thermal energy. Heat or thermal energy is further defined as the amount of
available molecules of kinetic energy transferred in a specific amount of time.
Heat is nothing if it is not transferred from one object to another. There are
many uses of heat energy. When we are cooking using our stoves, there is heat
energy. When we pour hot water onto our cup of coffee, there is heat energy.</span>
As the early universe cooled and expanded, the interaction that separated first from the four unified interaction is: the gravitational interaction
The gravitational interaction refer to the interaction between two objects that happened because of the mass and energy that they contained.
