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
