Science 8 Semester 1 Exam Review pt 2

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

Front

At what point does the biker have the greatest Potential Energy?

Back

Point B, where the biker is at the highest elevation.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of motion. It is the energy an object possesses due to its movement.

Front

What type of adaptation affects how an organism acts?

Back

Behavioral adaptation, which involves changes in behavior to better survive in an environment.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

Which equation represents the law of conservation of energy?

Back

Energy in = energy out.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is a Behavioral Adaptation?

Back

A Behavioral Adaptation is a change in behavior that helps an organism survive in its environment.
