I have collaborated in investigations to compare magnetic, electrostatic and gravitational forces and have explored their practical applications.

SCN 2-08a

Benchmarks:

· Measures gravitational force with a force meter or newton meter and records results using appropriate units (newtons).

· Explains how some objects may become electrically charged by rubbing two surfaces together and how the charges produce an electrostatic force.

· Investigates and demonstrates understanding that magnetic and electrostatic forces can both repel and attract.

· Describes practical applications of magnetic, electrostatic and gravitational forces, for example, magnetised needle in a compass.
