Motion
A straight path that something can move along
What is direction?
An object has more energy when it --
What is "moves fast"?
Making a complete spin on an axis
What is rotation?
The process by which one or more substances change to produce one or more different substances.
What is a chemical reaction?
This law states that matter cannot be created or destroyed
What is the law of conservation of mass?
A regular and repeated way in which something happens or is done
What is a pattern?
The ability to do work
What is energy?
This causes the sun to appear to move higher and then lower in the sky as the day progresses
What is Earth's rotation?
These signs of a chemical reaction occur when fireworks are set off
What are heat, light, and sound?
To maintain a constant overall total
What is conservation?
When enough force is applied to an object, it can change the object's --
What are speed or direction?
A change in position or location
What is movement?
These movements cause objects in our sky to appear differently
That is the rotation and revolution of Earth and the Moon
A substance that takes part in and undergoes change during a reaction
What is a reactant?
This energy is stored in all compounds and potentially released in chemical reactions
What is chemical energy?
Separate forces that combine to cancel each other out or make a net force of zero
What are balanced forces?
This is produced the faster you rub your hands together
What is increased heat energy?
An imaginary line that a sphere rotates around
What is an axis?
OF these, this is the one that is NOT evidence of a chemical reaction-- formation of a precipitate, change in state of matter, production of light, change in temperature
What is change in state of matter?
This is what we call it when the number and type of atoms of reactants is equal tothe number and type of atoms of products
What is a balanced chemical equation?
What are unbalanced forces?
Moving energy from oneobject or material toanother, or from one form to another
What is energy transfer?
The path an object takes as it revolves around another object in space
What is its orbit?
Physical and chemical characteristics of matter used to describe or identify a substance
What are properties?
A strong chemical bond that is formed when atoms share pairs of electrons
What is a covalent bond
