FLASHCARD QUESTION

Front

What is kinetic energy (KE)?

Back

The energy an object has due to its motion, calculated as KE = 1/2 mv² (1/2 x mass x velocity squared).

FLASHCARD QUESTION

Front

What does the PE vs. KE graph represent?

Back

It shows the relationship between potential energy and kinetic energy as an object moves, illustrating the conversion between the two forms of energy.
