Physics

Why is matter not charged?

• Because they don't haver charge

• Because the charge of a proton balances the charge of the electron

• Matter is charged

• Because the electrons come in pairs

How can you positively charge something?

• Adding electrons

• Adding protons

• Removing electrons

• Removing protons

Why is charge conserved?

• The electrons acquired by an object are lost by the other object

• Energy is not created nor destroyed, only transformed

• Because they flow evenly

• The charge moves in both directions

Why do we use q for charge

• Quick transfer

• Quad motion

• Quantised number

• Charge comes from latin: "Quarga"

Coulomb's law describe:

• The motion of charges

• The force between charges

• The proportion between charges

• The charge of an object

Given this diagram, the missing source must be:

• Negative

• Positive

What is current?

• The flow of charge

• The potential of motion

• The flow of energy

• Motion of energy

What is Resistance?

• An electrical quantity that measures how a device resist to motion

• An electrical quantity that measures how a device or material reduces electric current

• An electrical quantity that measures how a device resist to energy

• An electrical quantity that measures how a device reduces energy

Good conductors:

• Have low resistivity

• Have high resistivity

What is voltage?

• What creates electricity

• What creates energy

• What creates current

• What creates volts
