What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the significance of the average in data analysis?

Back

The average provides a summary measure that represents the central tendency of a data set.

Front

What is equilibrium in terms of thermal energy?

Back

Equilibrium occurs when two objects in contact reach the same temperature and thermal energy is evenly distributed.
