6. Magnetism and Electricity When 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.

7. Wednesday, Feb. 3rd 7 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:

8. 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.

9. 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

11. 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.

12. Projectile Motion Projectile– anything that is thrown or shot through the air – A projectile follows a curved path and has: and Horizontal Motion VERTICALVERTICAL M O T I O N

13. 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
