"6th Grade - Energy Vocabulary - 02"

QuestionAnswer
Factor A characteristic that can be measured
Potential energy Energy that is stored to be transformed at a later time
Elastic potential energy Stored energy released when an object’s shape is changed (as in a stretched rubber band or a coiled spring)
Gravitational potential energy Stored energy of an object based on its position above the ground
Work A way to increase (or decrease) an object’s energy by using a force to change the object’s motion or position
Force A push or pull that acts on an object
Compressed Squeezed or pressed together
Gravity The force of attraction between any two masses. Near the Earth’s surface, gravity is the force that attracts objects toward the center of Earth
System A collection of objects that interact
Mechanical energy The sum of the kinetic energy, gravitational potential energy, and elastic potential energy in a system
Conservation of mechanical energy If there is no friction or air resistance, the mechanical energy of a system changes only if the system does work on something else or energy is added from outside the system
Control variables Conditions or procedures that are held constant
Independent (manipulated) variable A factor that is changed o affect changes in the dependent (resulting) variable
Dependent (resulting) variable A factor that is affected by changes in the independent (manipulated) variable
Interpret To find the meaning of something
Trend A pattern or a tendency you can see over a broad range of data
Claim A statement that draws a conclusion about a set of facts or data
Acceleration The rate at which speed changes
Deformed Changed in shape because of an applied force
Elasticity Ability of a material to return to its original shape after it is deformed
Elastic limit Limit beyond which a deformed material does not return to its original shape
