Biomechanics - Linear Motion
Linear motion - Answer-when a body moves in a straight or curved line, with all its parts moving the
same distance in the same direction and at the same speed (e.g. skeleton bobsleigh)
force - Answer-a push or pull that alters the state of motion of a body
Newton's first law of motion - Answer-a body continues in a state of rest or of uniform velocity unless
acted upon by an external force
inertia - Answer-the resistance of a body to change it's state of rest or motion
Newtons second law - Answer-when a force acts on an object, the rate of change of momentum
experienced by the object is proportional to the size of the force and takes place in the direction in
which the force acts.
Also f=ma
what is momentum? - Answer-the quantity of motion possessed by a moving body. momentum=mv
what are the units for momentum? - Answer-kgms^-1
