Sherlock Ohms
This type of energy is called "stored energy' and typically is due to the position of the object. It can be converted to kinetic energy.
What is Potential Energy?
In the Bridge Building Challenge, this geometric shape was shown to provide stronger support.
What is the triangle or truss?
True or False: A metal rod is an insulator.
What is False? A metal rod is a conductor.
The flow of electric charge.
What is electric current?
True or False: In the Bridge Building Challenge, we proved that popsicle sticks are weak and can only support 80 pounds of weight.
What is False? We proved that a popsicle stick bridge can support over 200 pounds of weight.
A rigid bar that pivots about a fulcrum to multiply the force applied to one end. (hint: it helps us lift heavy items)
What is a lever?
This type of object does not allow the transfer of electricity, so it called an ____________. (hint: Styrofoam and plastic)
What is an insulator?
Newton's 3rd Law of Motion states that for any action, there is always an ________ and opposite action acting against it.
What is equal?
This type of electric circuit has one path for current to follow.
What is a series circuit?
True or False: A plastic rod is a conductor.
______'s 1st Law of Motion states that unless acted on by an outside force, an object at rest will stay at rest, and an object in motion will stay in motion.
Who is Newton?
A type of simple machine that consists of a rope wrapped around a wheel. (hint: It helps us raise/lower heavy items)
What is a pulley?
The name for an object that allows the transfer of thermal energy (heat) or electric current. (hint: a metal rod is one)
What is a conductor?
In the Mouse Trap Car Challenge, this was the reason why some students chose to use rubber bands on the wheels.
What is traction?
(traction = the adhesive friction of a wheel on a surface...grip...which prevents spin out)
A series circuit is setup to contain 3 light bulbs. 1 bulb is removed from its holder. This then happens to the remaining light bulbs.
What is they turn off?
The energy of motion.
What is Kinetic Energy?
In the Mouse Trap Car Challenge, this part of the design acted as a lever.
What is the dowel rod/stick?
The Greek letter Delta, represented by a triangle, means this in scientific calculations. (hint: T2 - T1)
What is a: change in or the difference between?
This is the buildup of charged particles on the surface of an object.
What is static electricity?
Copper wire is covered in a plastic coating for this reason.
Plastic is an insulator, not a conductor of electricity. The plastic coating prevents the flow of electricity through it. This protects not only the current but also prevents people from being shocked by the current.
Name the law: Energy is not created or destroyed, it just changes forms.
What is The Law of Conservation of Energy?
The rate at which an object changes position, and the direction that it moves.
What is Velocity?
In the Mouse Trap Car Challenge, when the car is wound up and the lever is pulled back ready to be deployed, the car has this kind of energy.
What is potential energy?
These kinds of charges attract each other.
What is opposite?
This type of electric circuit has multiple pathways for current to follow.
What is a parallel circuit?
