a force opposing the motion of n object due to fluid (e.g. air) flowing past the onject as it moves
Change in velocity per second.
[Elastic potential energy]
energy stored in an elastic object when work is done to change its shape
Two or three insluated ires surrounded by an outer layer of rubber or flexible pastic.
a electromagnetic switch that opens and cuts the current off if too much current passes through iy
metal rod used to absorb excess fission neutrons in a nuclear reactor so that only one fission neutron per fission on average goes on to produce further fission
a force can change the motion of an object in (newtons, N)
[Gravitational field strength]
the force of gravity on an object of mass in 1kg
energy of a moving object due to its motion; kinetic energy=massXspeed(squared)
change of velocity per second when an object slows down.
