Unit1
Do organisms contain cells?
Organisms can be made up of one or more cells.
What is complex motion?
Complex motion can't be calculated because they are combination of more than one type of motions.
What is magnet?
It is s object that creates magnetic fields.
What is matter?
Anything that has mass and volume.
what is the universe?
It includes living things, planets, stars, galaxies, dust clouds, light, and even time
Who was Galileo?
He invented a telescope.
What is field force?
All force fields are vector fields. They are magnetic fields, gravitational fields, and electrical fields.Vector means that it has both side and directions like an arrow.
What is electricity?
Electricity is the flow of electrical power or charge.
what are property of matter?
The properties of matter include any traits that can be measured, such as an object's density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature,.
What is the sun?
The sun is a star. It is the closest star to the earth.
What is velocity?
Velocity defines the direction of the movement of the body or the object.
What is friction?
The action of one surface of an object rubbing on the surface of the other object. both rubbing against one another is call the friction.

what is the moon?
The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.
What is acceleration?
Acceleration is the rate of change of the velocity.
What is Newton's first law?
A stationary object with no outside force will not move.
What are waves?
A wave is a disturbance that moves energy from one place to another.
What are rocks?
A rock is a solid mass of geological materials.
Spring, Summer Fall and Winter.
What is motion?
When something is moving and changing position.
What is balanced and unbalanced moments?
Balanced forces do not result in any change in motion and unbalanced forces result change in motion.
Who is Newton?
He discovered the laws of gravity and motion and invented calculus.
What is the rock cycle?
The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another.
What are the reasons for the seasons?
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
