• series and parallel

In a series circuit

• if one lamp blows all the others will stop
• there are different currents in each bulb
• you need more than one switch to control each bulb
• the bulbs glow at maximum brightness

• a net force is needed
• no force is needed
• a push force is needed
• gravity is needed

• acceleration
• steady speed
• stopped
• either acceleration or deceleration
