physics glossary Flashcards
define speed
the rate of change in position of an object in any direction
define velocity
the distance covered by an object in unit time
define distance
measures the length between object without regard to direction
define acceleration
the rate of change in veolcity
define deeceleration
the slowing down of an object
define constant velocity
a velocity that does not change
define force
the push and pull of an object with mass that causes teh velocity to change
define unbalneced force
the force applied in one direction is greater then the force applied in the other direction.
define intertia
the onjects tendancy to rsist change to motion
define newtons frist law
an object at rest will remain at rest until an unbalnced force is acted apon it
define newtons second law
net force=mass x acceleration
define newtons thrid law
for every action there is an equal and opposite reaction
define energy transfer
the movenment of energy from one place to another
define energy transformation
the conversion of energy from one form of energy to another
define kinetic energy
the energy tranferred to an object due to its motion
