science Flashcards
is motion in two dimensions
projectile motio9n
the path that the projectile travels is called?
trajectory
the velocity the body attains is called?
terminal velocity
product of the force of impact and the time that force is being applied
impluse
when two or more separate bodies apply force on each other
collision
the sum of a body because it is moving
mechanical energy
the capacity to do work
energy
mechanical energy when a body is moving is called?
kinetic enrgy
is the mechanical energy “stored” in a body
potential energy
potential energy that goes against the pull of gravity would be called?
gravitational potential energy
is the maximum amount of force used on a body
elastic limit
is the energy transformation that does not contribute to the body kinetic or potential enrgy
non mechanical energy transformation
device that is used to redirect the added energy to a body
machine
machine can multiply an applied force is called?
mechanical advantage
the ratio of the distances is called?
ideal mechanical advantage
is a measurement of how the machine really functions
actual mechanical advantage
measure of how well a machine transforms the input energy into the output energy
mechanical efficiency
form of eneygy that is moving between two bodies
heat
the total kinetic energy in the system
thermal energy
id the transfer of heat by sheets or currents of moving fluids
convection
transfer of heat by electromagnetic waves from a heat source
radiation
is the degree of how hot or cold a body is
temperature
device that uses the flow of heat is
heat engines
the maximum height the projectile could reach
range
