What is motion?
When an object’s distance is changing from another’s
100
What are the two types of properties?
Chemical and physical properties
100
What is an example of a chemical reaction?
Baking a cake.
100
What is density?
The ratio of the mass of a substance to its volume
200
What is a vector?
A quantity that consists of both direction and magnitude
200
What is the model of the solar system we traditionally follow? or What is a model in which the Earth and other planets revolve around the sun?
The geocentric model
200
What is the number of columns in the periodic table
18
200
What is the formula used to find density?
Density=Mass/Volume [D=m/v]
300
What is a net force?
A combination of forces acting on one object
300
What are the eight planets in order from the sun?
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
300
What is the column of the periodic table all the way to the left filled with?
Alkali metals.
300
What is Pascal's principle?
A principle that states that pressure increases by the same amount throughout or confined fluid
400
What are the 4 types of friction?
Sliding friction, static friction, rolling friction, and fluid friction
400
What is the law that states that the total amount of matter in an object can be neither destroyed nor created during any chemical or physical change?
Law of Conservation of matter.
400
What is the difference between a chemical and physical reaction?
A chemical reaction is a process which a substance transforms into another. A physical reaction is a reaction that changes the physical features of a substance, i.e the texture, color, temperature, weight, etc., but ultimately does not change the internal structures
400
What is an example of a buoyant force and explain why it is one?
A ship made of steel can float because it can displace more water than it weighs, evidently creating a buoyant force.
