lesson 1 contact and non contact forcs Flashcards
what are the two different types of forces
contact forces
non contact forces
definition for force
a push or pull that acts on an object due to its interaction with another object
force is measured in what
newtons (N)
forces have what
magnitude and direction
forces are classed as what
vector quantites
why are forces classed as vector quantities
as they have both magnitude and direction
all forces are divided into which two groups
contact and non contact forces
contact forces are what
when the two objects are physically touching
non-contact forces are what
those that don’t require the two objects to be touching
what are examples of contact forces
friction
air resistance
tension
normal contact force
what are the types of non-contact forces
gravitational force
magnetic force
electrostatic force
what is a key feature within non-contact forces
the strength of the object decreases as the object gets further apart
