|
The rate at which velocity changes.
|
What is Acceleration (Newton's 2nd Law)
|
|
|
Equal forces acting on an object - will not cause a change in motion.
|
What is Balanced Force?
|
|
|
The potential of a chemical substance to undergo a transformation through a chemical reaction.
|
What is Chemical Energy?
|
|
|
The total amount of energy in an isolated system remains constant over time.
|
What is Conservation of Energy?
|
|
|
Energy created by a generator.
E. |
What is Electromagnectic Energy?
|
|
|
An indirectly observed quantity, often understood as the ability a physical system has to do work on other physical systems.
|
What is Energy?
|
|
|
A push or a pull, f=mxa
|
What is a force?
|
|
|
The force that two objects exert against one another when they rub against each other.
|
What is Friction?
|
|
|
The force that pulls objects towards each other.
|
What is Gravity?
|
|
|
The tendancy of an object to resist change in motion.
|
What is Inertia?
|
|
|
Physical energy.
|
What is Kinetic Energy?
|
|
|
A body of observations.
|
What is a law?
|
|
|
How much matter an object has.
|
What is Mass?
|
|
|
Both kinetic and potential energy.
|
What is mechanical energy?
|
|
|
The overall forces acting on an object.
|
What is Net Force?
|
|
|
The unit for force.
|
What is Newton (as a unit)?
|
|
|
Fission and fusion
|
What is nuclear energy?
|
|
|
Energy that is held.
|
What is potential energy?
|
|
|
Rise over run.
|
What is the slope (of the line)?
|
|
|
Energy from the sun
|
What is solar energy?
|
|
|
Energy traveling via sound.
|
What is sound energy?
|
|
|
Distance an object travels in a certain amount of time. s=d/t
|
What is speed?
|
|
|
A group of entities working together
|
What is a system?
|
|
|
A body of experiments.
|
What is a theory?
|
|
|
Heat energy.
|
What is thermal energy?
|
|
|
The movement of energy from one object to another
|
What is the transfer of energy?
|
|
|
The changing of energy from one form to another.
|
What is Transform (energy)?
|
|
|
Causes motion (therefore, an unbalanced force causes acceleration)
|
What is unbalanced force?
|
|
|
Explain the difference between a theory and a law.
|
A law is a body of observations that provide for constants and a theory is a body of experiments that explain how concepts work.
|
|
|
Describe the relationship between force, mass, and acceleration (Newton's Second Law)
|
Force = Mass X Acceleration
|
|
|
Describe how a net force (gravity, friction, balanced, unbalanced) produces change in motions.
|
Gravity = Force pulling objects towards each other, Friction = the force that objects exert against one another, Balanced = equal and Unbalanced = causing motion / acceleration
|
|
|
Every action has an equal and opposite reaction.
|
What is Newton's 3rd Law?
|
|
|
Calculate speed using S=d/t when the speed is 40 and the distance is 120.
|
3
|
|
|
The idea that speed never changing is a straight line.
|
What is Straight-Line motion?
|
|
|
Compare the relative amount of potential energy and kinetic energy of a moving object at different points along its path.
|
When going downhill, kinetic energy increases and potential decreases. The opposite is true going up hill.
|
|
|
Societal Issues?
|
Lack of heating oil / coal for a community = nuclear or solar.
|
|
|
Energy transformations from the sun to a toaster
|
Solar energy transforms to electrical.
|
|
|
Law of Conservation of Energy
|
total amount of energy in an isolated system remains constant over time
|
|
|
Apply the law of conservation of energy.
|
