FORCES There are different types of forces. AIR RESISTANCE FORCE APPLIED FORCE Applied force is when you put force or apply force to an object. SPRING FORCE FRICTIONAL FORCE Frictional Force is when you push or pull an object and you create friction under the object. GRAVITATIONAL FORCE NORMAL FORCE ELECTRICAL FORCE MAGNETIC FORCE A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field.
