Live Science: Static Electricity

My name is Dave and welcome to the Science Museum of Virginia. Electricity is the energy created by moving negative charges or negative ions. Over here I have a Van de Graaff generator, so let’s see what happens when negative gets near a positive. Ah what do you see? We’re experiencing a discharge of static […]

(2 of 2) Electricity and Magnetism – Review of All Topics – AP Physics C

Mr. P: Ammeters and voltmeters. An ammeter, you need to put in series, a voltmeter, you need to put in parallel. In order to measure the current, in order to put it in, you need to have it in series, right? In order to have little change to the circuit, you need to have as […]

How Electrons Become Electricity

How electrons become electricity. Electrons are negatively charged particles in atoms. Electricity is the flow of electrons and a force is needed to move electrons. First we need to look at forces. Forces either push objects apart or pull them together. Gravity is a force of attraction that pulls objects together. Imagine sitting on a […]

Electricity & Magnetism Hand Rules (part one)

Electricity and magnetism are intently related. We use moving magnets to generate electric current, as with these turbines, and electric current to make magnets. Here I’ve set up a powerful magnet with a strip of aluminum foil running perpendicular to the magnetic field lines. Remember these from the last episode? Well, I’ve set up a […]

(1 of 2) Electricity and Magnetism – Review of All Topics – AP Physics C

Bo: Hey, guys! Billy: Hey, Bo! Bobby: Hi, Bo! ♫ (lyrics) Flipping Physics ♫ Mr. P: Ladies and gentlepeople, the bell has rung, therefore class has begun. Therefore, you should be seated in your seat, ready and excited to review everything we learned in electricity and magnetism in AP Physics C. Here we go, are […]

‘Hey Bill Nye, How About Hydraulic Knees?’ #tuesdayswithbill

Hi. I’m at Patrick Lee from Deerpath Middle School. I’m in fifth grade. And my question is do you think hydraulics could help people with knee problems when their knee breaks down and it could help it go down much softer? Patrick, let me start by saying that is a fabulous tie. Way to go […]

Space Force, AF Housing, Operation Christmas Drop

I’M STAFF SERGEANT GREG CERNY WITH YOUR LOOK AROUND THE AIR FORCE. SECRETARY OF THE AIR FORCE BARBARA BARRETT SPOKE ON THE IMPORTANCE OF A SPACE FORCE DURING THE 2019 REAGAN NATIONAL DEFENSE FORUM. ‘AMERICA IS THE BEST THERE IS AT SPACE. AMERICA IS ALSO THE BIGGEST USER OF SPACE. WE KNOW WE ARE NOW […]

Why the Weak Nuclear Force Ruins Everything

[♪ INTRO] The weak nuclear force gets short shrift among the four fundamental forces of nature. People wax on about the marvels of gravity that holds entire worlds together. They’ll detail electromagnetism, which lets us see and keeps us from falling through the floor. They’ll even praise the strong nuclear force that fights to keep […]

PM-1 Nuclear Power Plant

Behind me stands the remains of the PM-1 nuclear power station atop Warren Peak near Sundance Wyoming. The PM-1 nuclear power station was the first portable nuclear power station ever constructed in the United States. The Pm-1 power station was designed to operate 3 large radars. Warren Peak in the Bearlodge Mountains made the perfect […]

Nuclear power generation | Nuclear Physics | meriSTEM

When it comes to electricity generation the only real difference between a coal-fired power plant and a nuclear power plant is in the way that heat is generated. In an efficient reactor the heat liberated by nuclear fission is in the form of kinetic energy of the fission fragments. This energy is used to heat […]
