Gravity
This song, sung famously by Cynthia Erivo, Ariana Grande, Kristin Chenowyth, and Idina Menzel, is beloved by many Broadway fans.
What is "Defying Gravity?"
This is a type of material that does not allow electric current to pass through it.
What is an insulator?
Every magnet has two of these (North and South) where their forces is exerted the strongest.
What are poles?
This is the flow of electrons.
What is electrical current?
This noncontact force connects all life forms in the galaxy and is strengthened by a high concentration of midi-chlorians. It is used by both Sith and Jedi to achieve their goals.
What is The Force (from Star Wars).
This is the acceleration of all objects on Earth, if there was no air resistance.
What is 9.8 m/s/s.
This is a type of material that easily allows electric current to pass through it.
What is a conductor?
This is created by running electricity through a coil of wires, producing a magnetic field.
What is an electromagnet?
This is opposition to the flow of electrons.
What is resistance?
This is the equation described by Newton's second law, that allows you to calculate a force.
What is force = mass * acceleration?
This is the disk-shaped pattern that objects held by the gravitational force of another object fall into.
What is an orbit?
This is a material that sometimes allows electric current to pass through it.
What is a semiconductor?
These are the three materials commonly affected by magnetic forces.
This type of diagram gives a prediction of how force will act on an object. It can be used to show the impact of noncontact forces such as gravity, electricity, and magnetism.
What is a force field?
This is an attractive, non-contact force between all objects with mass.
What is gravity?
The ________________ of an object never changes, but its ________________ may change depending on how much gravity pulls on it.
What are mass and weight?
This property results from the transfer of electrons from one object to another, leaving one with an excess of electrons, and one with an excess of protons.
Double points:
______________ charges attract, while ______________ charges repel.
What is electric charge?
Double:
Opposite, same
This is a machine that uses the movement of magnets to move electrons in loops of wire and produce electricity.
Lines in a force field typically look like this.
What is curved, never overlapping, and with arrows pointing in the correct direction. (at least one correct for points)
This noncontact force can only exist when at least one object has either an imbalance of electrons. It may be either attractive or repulsive.
What is electrical force?
When ___________________ increases, strength of gravity increases.
When ___________________ increases, strength of gravity decreases.
What are mass and distance?
When ___________________ increases, strength of electrical force increases.
When ___________________ increases, strength of electrical force decreases.
What are strength of charge and distance?
These two forces can be used to produce each other because they both cause the movement of electrons.
What are magnetism and electricity?
Force fields have arrows that point...
...in a gravitational field, towards the object with the _______________.
... in an electrical field, from ________________ to _______________.
... in a magnetic field, from S to N ______________ the magnet, and N to S _____________ the magnet.
What is ...
strongest gravitational pull?
positive to negative?
inside / outside?
This noncontact force can be either attractive or repellant, and must involve specific materials, usually metals.
What is magnetic force?
