Energy
The energy possessed by an object due to its motion
what is kinetic energy
This star is at the center of our solar system.
What is the Sun?
These waves require a medium, such as air, water, or solids, to travel.
What are mechanical waves?
This Process occurs when organisms with helpful traits survive and reproduce more often
What is natural selection?
This force pulls things toward the earth
what is gravity?
This is the ability to do work or cause change.
What is energy?
This process powers stars by combining hydrogen atoms into helium.
What is nuclear fusion?
This part of a wave is the highest point above the rest position.
What is a crest?
These are characteristics that help an organism survive in its environment
What are Adaptations?
This scientist created the theory of gravity
who is Issac Newton?
the 2 categories of energy
what is Potential and kinetic energy
The color of a star can indicate this property.
What is its temperature?
The distance from one crest to the next crest is called this.
What is wavelength?
This scientist Developed the theory of natural selection
Who is Charles Darwin?
The measure of the force of gravity acting on an object is called this.
What is weight?
Stored energy is known as this type of energy.
What is potential energy?
These are massive clouds of gas and dust where stars are born.
What are nebulae?
This measures the number of waves that pass a point in one second.
What is frequency?
Natural selection requires this variation among the population
What is genetic Variation?
Gravity keeps this natural satellite orbiting the Earth.
What is the moon?
Energy cannot be created or destroyed according to this law.
What is the Law of Conservation of Energy?
A star like the Sun spends most of its life in this stage.
What is the main sequence?
The lowest point of a wave below the rest position is called this.
What is a trough?
A trait that improves survival of a spices and becomes common over time
What is a beneficial trait?
This value describes the acceleration due to gravity on Earth.
What is 9.8 meters per second squared?
