Front

What does high species diversity indicate in an ecosystem?

Back

A healthy ecosystem with a wide variety of species coexisting.

Front

As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy?

Back

The potential energy decreases while the kinetic energy increases.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.
