What does Newton’s first law state?
a) A body at rest tends to remain at rest and a body in motion tends to remain in motion at
a constant acceleration unless acted on by a net external force.
b) A body at rest tends to remain at rest and a body in motion tends to remain in motion at
a constant velocity unless acted upon by an external force.
c) The rate of change of momentum of a body is directly proportional to the external force
applied to the body.
d) The rate of change of momentum of a body is inversely proportional to the external
force applied to the body.
