What does Newtons 1st law of motion state about objects on which forces are balanced?
Newton's first law says "Every body remains in a state of constant velocity unless acted upon by an external unbalanced force." This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant velocity.Newton's first law for moving objects with balanced force is that the object "behaves" like it has no force acting on it. Because the object has balanced force, the object has a net force of zero, and according to Newton's first law, an object that is in motion will not change its velocity unless an unbalanced force acts upon it. The object is therefore in uniform motion (aka moving at constant velocity).
How does Newtons second law measure force?
Unbalanced force=mass of object x acceleration of object
How does unbalanced force help move an object?
An unbalanced force acting on an object causes a change in its motion by accelerating it in the direction of the force. This acceleration results in the object moving. The greater the unbalanced force, the greater the acceleration and speed of the object.
What are the three types of forces according to newtons first law?
Sir Isaac Newton first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1686. His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force resulting from unbalanced forces acting on an object (if all the external forces cancel each other out), then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. And if an additional external force is applied, the velocity will change because of the force. The amount of the change in velocity is determined by Newton's second law of motion.
Can an object have zero velocity and nonzero acceleration?
Yes, an object can have zero velocity and nonzero acceleration. This occurs when the object is changing its direction but not its speed. For example, in circular motion, the object's velocity is constantly changing direction, leading to a nonzero acceleration even when its speed is constant.
How does an unbalanced force affect a moving object at a constant velocity?
If the group of forces on an object is unbalanced, then the object can't have constant velocity. Its speed or the direction of its motion must change.
Does unbalanced forces maintain motion at constant velocity?
No. If the forces on an object are unbalanced, that means their sum is not zero, and there is a net force on the object. Since there is a net force on it, the object is accelerated, which is another way of saying that its velocity changes.
When no unbalanced forces act on an object the object can have no?
If forces on an object are balanced, the object will not accelerate - i.e., its velocity won't change.
What will happen to an object at rest if no unbalanced forced act on it according to Newtons First Law?
An object at rest will remain at rest, and an object in motion will continue to move with a constant velocity in a straight line if no unbalanced forces act on it, according to Newton's First Law of Motion.
What happens to the velocity of an object when balanced force act on it?
The velocity is constant and there is no net or unbalanced force.
If an unbalanced force acts on an object will it move at constant velocity?
No, an unbalanced force will cause an object to accelerate, not move at a constant velocity. The object will continue to accelerate in the direction of the unbalanced force until a balanced force is applied.
Do balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
What change occurs to the mass of an object when an unbalanced force is applied to it?
There will by no change in the mass, which is constant, but the unbalanced force will cause the object to accelerate. Acceleration can be in a positive direction or a negative direction ("deceleration"), or it can be circular, in which the acceleration changes constantly, even if the velocity remains constant.
What happens when forces are balanced and unbalanced?
When forces are balanced, the object remains at rest or continues to move at a constant velocity. When forces are unbalanced, there is a net force acting on the object, causing it to accelerate in the direction of the greater force.
Why there must be an unbalanced force acting if an object is moving in a circle at constant speed?
If an unbalanced force was not acting upon it, it wouldn't be moving in a circle.An object with no unbalanced force will either not be moving, or be moving in a straight line due to Isaac Newtons 1st law of motion.
What is a force that can cause an object to change its speed and direction?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
What law that states that every object maintain constant velocity unless acted on by an unbalanced force?
Newton's 1st law'
