An object in motion will stay in motion and an object at rest will stay t rest until acted upon b an unballanced force
how force mass and acceleration are related (force=mass*acceleration)
for every action there is an equal and opposite reaction
Mass of an object * it's velocity; determines how dificult it is to stop the object's motion
a push or a pull that gives energ, sometimes causing a change in object's motion
your body has ___
surface resistance to relative motion, as of a body sliding or rolling
true of false: law 1 has unballanced forces
true or false: law 2 has unballanced forces
how many forces are constantly acting upon us
al forces occur in ___
depends on mass of object and velocity whith witch it is traveling
all moving objects have ___ becausse of velocity
true or false: the more momentum an object has the ahrder it is to stop (inertia)
an increase in ___ or velocity will increase momentum
momentum is always ___
the movement of an object that is not moving is ___
true or false: momentum is in the same direction as velocity of the object
momentum can be transfered to a ___ object when they collide
in order for forces they need to have a net force of ___
i forces are equal but in opposite direction they are ___
if forces are equal but in same direction they are ___
if forces are not equal but in opposite direction they are ___
if there is a change in momentum you combine by ___
forces that change in position of an object are ___
forces are measured in ___
