Work and Energy
If no work is done on an object by external forces, this will be conserved.
What is mechanical energy?
This is the time it takes to go around a circle one time.
What is the period?
This is the man who discovered gravity exists between all objects with mass.
Who is Newton?
This is the law that describes the electric force between two charged objects.
What is Coulomb's Law?
This is the hindrance to the flow of charge in a circuit.
What is resistance?
The sum of these two values is called mechanical energy.
What are kinetic energy and potential energy?
This is the direction of the net force acting on an object moving in a circle.
What is centripetal/inward?
According to this law, the force of gravity is inversely proportional to the square of the distance between the objects.
What is the inverse square law?
This term describes the movement of electrons throughout an object.
What is induction?
The rate that charge flows in a circuit is measured by these units.
What are Amps?
If negative work is done on an object, this will happen to the object's mechanical energy.
What is decrease (by the same amount)?
This is the direction of the velocity of an object moving in circular motion.
What is tangent?
If the mass of both objects doubles, this will happen to the force of gravity between them.
What is quadruples?
This term refers to the separation of charge within an object.
What is polarization?
The amount of energy gained by 1C of charge in the battery is referred to as this.
What is voltage?
If either of these two forces is the only force acting on an object, its mechanical energy will stay the same.
What are gravity and spring force?
The centripetal force of a roller coaster at the top of a loop is a combination of these two forces.
What are gravity and normal force?
This is Kepler's law that describes the speed of the planets as they orbit the sun.
What is the 2nd law/law of equal areas?
If a single conductor is charged by induction using a positive object, electrons will travel from this to this.
What is the ground to the conductor?
According to Ohm's Law, doing either of these things will increase the current flowing in the circuit.
What is increasing the voltage or decreasing the resistance?
A 1000kg car traveling at 25m/s that comes to a stop due to an 8000N force of friction will stop over this distance.
What is 39.1m?
This is the speed of an object that moves in a circle of radius 7m in a period of 5s.
What is 8.8m/s?
This is the shape of the orbit in which KE and PE are constant at each position.
What is circular?
If two objects attract each other with an electric force of 64 units and the distance between them is doubled, this will be the new force between them.
What is 16 units?
This is the equivalent resistance of a parallel connection of a 4 Ohm, a 12 Ohm, and a 6 Ohm resistor.
What is 2 Ohms?
