According to Newton's Laws of Motion, objects will continue in a straight line at a constant velocity unless acted on by an outside force.
To determine the missing terms in the statement, we need to understand Newton's First Law, also known as the law of inertia. This law 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 unbalanced external force.
Now, let's break down the missing terms:
1. The missing term after "constant" describes the speed at which the object is moving. In this case, it is referred to as "velocity." Velocity includes information about both the speed (how fast an object is moving) and the direction of the motion.
2. The missing term after "outside" represents any force that is not generated by the object itself. This force is referred to as an "external force." External forces can come from various sources, such as gravity, friction, air resistance, or forces applied by other objects.
In summary, an object will continue moving in a straight line at a constant velocity unless acted upon by an outside force.
