Term
Law of Conservation of Energy
Definition
"States that energy cannot be created or destroyed, but can only be transformed from one form into another"
Term
Transferring Kinetic Energy
Definition
Kinetic energy can be transferred from one object to another when they collide.
Term
Potential Energy
Definition
Energy that is stored due to position
Term
Energy
Definition
"Ability to cause change; can change the speed, direction, shape, or temperature of an object"
Term
Converting Kinetic to Potential Energy
Definition
Kinetic energy is transformed into potential energy when an object slows down and stops moving.
Term
Relationship between mass & kinetic energy
Definition
The amount of kinetic energy an object has depends on the mass of the object. More mass = more kinetic energy.
Term
Increasing Potential Energy
Definition
"The higher an object is lifted, the greater its potential energy."
Term
Relationship between speed & kinetic energy
Definition
"Kinetic energy depends on speed. The faster an object moves, the more kinetic energy it has. Kinetic energy increases as speed increases."
Term
Kinetic Energy
Definition
Energy an object has due to its motion
Term
Energy Transformation
Definition
Occurs if energy changes from one form to another. Energy transformations go on all around you and inside of you all the time.
Term
Converting Potential to Kinetic Energy
Definition
Potential energy is transformed into kinetic energy when an object starts to move.
Term
Temperature
Definition
Measure of the average kinetic energy of an object's atoms
Term
Thermometer
Definition
Tool for measuring temperature
Term
What are freezing and boiling points in the Farenheit scale?
Definition
Freezing point is 32 degrees
Boiling point is 212 degrees
Term
What are freezing and boiling points in the Celsius scale?
Definition
Freezing point is 0 degrees
Boiling point is 100 degrees
Term
Heat
Definition
Transfer of energy from one object to another due to a difference in temperature
Term
What are the 7 forms of energy?
Definition
Light, heat, chemical, nuclear, mechanical, electrical, and sound
Term
Conduction
Definition
transfer of energy by collisions between atoms; usually occurs in solids
Term
Convection
Definition
transfers heat when particles move between objects or areas that differ in temperature; most common in gases and liquids
Term
Chemical reactions ___ energy.
Definition
release
Term
Endothermic reactions
Definition
chemical reactions that absorb energy
Term
Exothermic reactions
Definition
chemical reactions that release energy
Term
Catalyst
Definition
a substance that changes the rate of a chemical reaction without any change to its own structure
Term
Thermal Insulators
Definition
materials that are poor conductors of heat; examples air, plastic, cloth
Term
Thermal Conductors
Definition
materials that are good conductors of heat; examples- metals
