Sample Learning Goals

Explain the relation between the size and direction of the blue electric field lines to the sign and magnitude of the charge of a particle. Explain the interactions between two charged particles and explain why they move as they do. Explain what happens when you apply different external electric fields.

Move point charges around on the playing field and then view the electric field, voltages, equipotential lines, and more.

Umiestnite bodové náboje na plochu a potom sledujte elektrické pole znázornené intenzitou elektrického pola, elektrickým potenciálom a ekvipotenciálnymi hladinami.

Sample Learning Goals

Determine the variables that affect how charged bodies interact. Predict how charged bodies will interact. Describe the strength and direction of the electric field around a charged body. Use free-body diagrams and vector addition to help explain the interactions.

Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone of the popular simulation of the same name marketed by Physics Academic Software and written by Prof. Ruth Chabay of the Dept of Physics at North Carolina State University.

Zahrajte si hokej s elektrickým nábojom. Umiestnite na ľad elektrické náboje tak, aby sa puk dostal do bránky. Môžete tiež zobraziť elektrické pole a trajektóriu puku. Ak umiestnite pred bránku prekážky, tak dať gól bude dosť ťažké, ale je to možné.

Why does a balloon stick to your sweater? Rub a balloon on a sweater, then let go of the balloon and it flies over and sticks to the sweater. View the charges in the sweater, balloons, and the wall.

Prečo sa balón prichytí váš sveter? Pošúchajte balón o sveter, vzdiaľte ho od svetra a pustite ho. Balón opäť priletí k svetru. Priložte balón k múru a oň zostane na ňom prichytený. Prečo? Všimnite si elektrický náboj na svetri, balóne a múre.

Describe and draw models for common static electricity concepts (transfer of charge induction attraction repulsion and grounding)

Make sparks fly with John Travoltage. Wiggle Johnnie's foot and he picks up charges from the carpet. Bring his hand close to the door knob and get rid of the excess charge.

John Travolt alias John Napäťový môže byť zdrojom elektrickej iskry. Šúchaním jeho topánky po koberci sa z koberca premiestni elektrický náboj na jeho telo. Ak chytí rukou kľučku dverí, tak preskočí elektrická iskra. Skúmajte na akú vzdialenosť sa musí priblížiť ku kľučke, aby preskočila iskra. Je tá vzdialenosť vždy rovnaká a ak nie, tak od čoho závisí?
