 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An object at rest will ____ if no outside forces are applied.
 A Stay at rest B Increase Velocity C Decrease Mass D None of the above
Explanation:

Detailed explanation-1: -Newtonâ€™s first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.

Detailed explanation-2: -Inertia is the tendency of all objects to resist any change in motion. Inertia causes a moving object to stay in motion at the same velocity (speed and direction) unless a force acts on it to change its speed or direction. It also causes an object at rest to stay at rest.

Detailed explanation-3: -An object remains in the state of rest or motion until any force is applied because of its inertia.

Detailed explanation-4: -Explanation: The net force that acts upon an object is equal to zero when that object is at rest. The net force acting on an object is equal to the sum of the vectors of all the forces that are acting on the object.

Detailed explanation-5: -Answer. The object is initially at rest. For the object to remain at rest with forces acting on it, the velocity of the object must not change. This means that the forces acting on the object must be balanced.
