Newton’s First Law is the
law of inertia
. An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity.
What is a possible state of an object in the absence of a net force at rest zero acceleration constant speed all of these?
What is a possible state of an object in the absence of a net force? at rest, zero acceleration and constant speed. What term refers to the tendency of an object to remain at rest or in uniform, straight-line motion?
inertia

Is it possible to have motion in the absence of a net force?
Yes,
it is possible to have motion without a force being present
. Newton’s first law states that, in fact, an object must continue to move at the same…
What term refers to the tendency of an object to remain at rest or to remain in uniform straight line motion?
Law of inertia
, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
What is absence of force?
“In the absence of a net force acting on it,
an object at rest will remain at rest
and an object in motion will continue in motion at constant speed in a straight line” When the net force on an object is zero, it does not necessarily mean there are no forces acting on the object.
What is the direction of the net force?
Direction of Net Force:
The direction of the net force (or unbalanced force) acting upon an object is
the same as the direction of the acceleration
. Objects which move in a circle at a constant speed are accelerating. The acceleration is directed towards the center of the circle.
What is the force of an object if it is not accelerating?
If there is no acceleration, then the object will move with a constant velocity. Mathematically, we can look at Newton’s second law and the formula for acceleration. We know that the
force is zero
. Since we know that the mass cannot be zero, the acceleration must be zero.
The net force gives
acceleration to the particles
or objects in motion who moves from one place to another due to this acceleration . So when a net force is applied it tries to move the body or the object .
Can things move without force?
In the absence of any forces,
no force is required to keep an object moving
. … An object’s velocity will only remain constant in the absence of any forces or if the forces that act on it cancel each other out, i.e. the net force adds up to zero.
What would be the net force on an object if the object is traveling a constant velocity?
Explanation: If an object is moving with a constant velocity, then by definition it has zero acceleration. So
there is no net force acting on the object
. The total work done on the object is thus 0 (that’s not to say that there isn’t work done by individual forces on the object, but the sum is 0 ).
Is it true if an object is at rest inertia will keep it at rest?
Inertia is the tendency of an object to resist a change in its motion.
If an object is already at rest, inertia will keep it at rest
. If the object is already moving, inertia will keep it moving. … Objects with greater mass also have greater inertia.
What keep the object remain at rest?
Inertia
. … Inertia is the property of a body to remain at rest or to remain in motion with constant velocity. Some objects have more inertia than others because the inertia of an object is equivalent to its mass.
What keeps the object remain at rest answer?
Inertia
is a force which keeps stationary objects at rest and moving objects in motion at constant velocity. Inertia is a force which brings all objects to a rest position. All objects have inertia. A more massive object has more inertia than a less massive object.
What is the absence of net force?
Newton’s First Law is the law of inertia. An object with no net forces acting on it which is initially at
rest will remain at rest
. If it is moving, it will continue to move in a straight line with constant velocity.
Is a push or pull force?
A
push is force that moves away from you
. A pull is a force that comes towards you.
What forces are when the net force on an object is not zero?
– If the net force on an object is not zero, it is not in
equilibrium
(that is, a change in velocity will occur), and thus Newton’s Second Law must be used to determine its motion. Two vectors A and B are equal if they have the same magnitude and direction, whether or not they have the same initial points.
