Bell-ringer: Get out notebooks and folders and open to your “Electrical circuits” notes.
Agenda:•Complete “Circuit Drawing Practice” worksheet•QUIZ TOMORROW!•Finish “Magnetism and Electricity” notes
•Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. (S.7.PS.8)
Objective:
Series Circuit• Current has only one
loop to flow through.
• Examples: light bulbs, holiday lights
• Contains two or more branches for current to flow through.
• Examples: homes, automobiles
Parallel Circuit
Complex circuit: a circuit composed of both series and parallel circuits

Magnetism and ElectricityWhen electric current flows through a wire, a magnetic field forms around the wire.
Wire
Strength of magnetic field depends on the amount of current flowing in the wire.

Bell-ringer: Discuss with your neighbor:1. When electric current flows
through a wire, a _____forms around the wire.
Agenda:•Bell-ringer•Finish “Magnetism and Electricity” notes•Begin “Gravity” notes
•Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. (S.7.PS.8)
Objective:
• Electromagnets– a temporary magnet made by wrapping a wire coil carrying a current around an iron core.– To increase strength of the magnetic field, add more
turns to the wire coil (solenoid) or increase the current passing through the wire
• Electric motor – a device that changes electrical energy into mechanical energy– In a simple electric motor, an electromagnet rotates
between the poles of a permanent magnet.
Direct and Alternating Current• Direct Current (DC) –
current that flows in only one direction through a wire.
• Example: a battery
• Alternating Current (AC) – reverses the direction of the current flow in regular patterns.
• Example: plugging a toaster into a wall outlet

Gravity
Gravity– any two masses that exert an attractive force on each other – Gravity depends on mass and distance between objects
Weight– gravitational force exerted on an object; measured in units called Newtons– The greater the objects mass, the stronger the
gravitational force on it.
Projectile Motion• Projectile– anything that is thrown or shot through
the air– A projectile follows a curved path and has: and
Horizontal Motion
VERTICAL
MOT ION
Centripetal Force• Centripetal acceleration– acceleration toward the
center of a curved or circular path– “centripetal” means toward the center
• Centripetal force– force acting toward the center of a curved or circular path
