Back

Electrical → thermal → light

Front

What is the unit to MEASURE force?

Back

Newton

Front

Why is the net force 0 when two elephants pull with equal force in opposite directions?

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?
