If no outside force acts on the object, it will continue to move in a straight line at a constant speed. This is known as Newton's First Law of Motion, also called the law of inertia, which states that an object at rest will remain at rest and an object in motion will remain in motion with a constant velocity, unless acted upon by an external force.
If no outside force acts on an object moving in a straight line at a constant speed, the object will continue to move in the same direction at the same speed. This is stated in Newton's First Law of Motion, also known as the law of inertia. According to this law, an object will simply maintain its state of motion unless acted upon by an external force. In the absence of any external force, there will be no change in the object's speed or direction of movement.
