"6th Grade - Energy Vocabulary - 02"
Question | Answer |
---|---|
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 |
