Answer:
Step-by-step explanation:
Newton's first law of motion states that objects at rest will remain at rest, while objects in motion will remain in motion with a constant velocity unless acted upon by a net external force. This is also known as the law of inertia. Inertia refers to an object's resistance to a change in its state of motion. An object with a greater mass will have greater inertia and require more force to change its motion. Essentially, objects will continue to do what they are doing, whether at rest or in motion, until an external force changes that. This law is applied in many everyday situations, from a book remaining on a table unless someone picks it up, to a car continuing to move forward even after the driver slams on the brakes.
