Motion is a one of the key topics in

physics and in particular in mechanics

can control, start and stop the flow of electrons

to act upon an object to get it moving or to change its motion

- A battery and a dynamo can

transform a source of energy into electric energy

has a blockage made of empty space

Conductance depends on the capacity of a material to

to hold back and release electric

Mechanics includes disciplines like

statics, dynamics, kinetics and aerodynamics

is the study of moving bodies and forces

Scientists have discovered

several rules laws that explain functions and causes of changes in motion

has a complete metal path with no blockages

Alternating current is

the best to transmit current over long distances

In alternating current

electrons keep changing direction at regular intervals

Aerodynamics focuses on

the forces acting on solid bodies moving through the air

is the device that uses electricity to work

bodies at rest and studies the forces that balance one another

In insulators electric charges

occupy free positions and can't move very easily

The speed of an object can be influenced by

switch, utilizer, generator, conductor

What does voltage measure?

measures the quantity of energy that electrons are carrying
