Lift, trust, drag and gravity is the Newtons first law of Motion Newton's laws of motion are: 1) Every object in a state of motion will remain in that state unless and exter â¦ nal force is applied.2) Acceleration is produced when a force acts on a mass.nswer: #1) Inertia: An object in motion tends to stay in motion unless acted upon by an outside force. An object at rest tends to stay at rest unless acted upon by an outside force. #2) Constant Acceleration: The relationship between and it's acceleration and the applied force is stated by F=ma.
