Newton's second law of motion leads to the formula for acceleration which is a measure of the rate of change of velocity per unit time and, if you solve for positive acceleration, reveals how much net force is needed to overcome an object's mass. The formula for acceleration is \(\vec{a} = { \vec{F} \over m }\) or, solving for force, \(\vec{F} = m\vec{a}\).
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
An exoskeleton (external skeleton) is common in arthropods like insects, spiders, and crustaceans.
Force is applied to change an object's speed or direction of motion.
Radiation occurs when electromagnetic waves transmit heat. An example is the heat from the Sun as it travels to Earth.
