Question

According to Newton's _______ Law of motion, any object that is accelerating must be experiencing a _______ force.
Second, Net
Third, Large
Third, Small
First, Negative
First, Positive

Answer 1

accelerating object ? i think second and net.

Answer 2

im confused with this one

Answer 3

if any object is accelerating, there have to be a force acting on it.

Answer 4

i dont understand still

Answer 5

I'm srry. If the first blank is first law then the second one should be "unbalanced force" so my explanation is wrong. .. it has to be @oksuz answer I think......

Answer 6

\[a=\frac{ F }{ m }\]

if F is different than zero, a have to be different than zero as well.

Here, F is net force acting on a body.

Answer 7

idk still cant understand it

Answer 8

Newton's first law of motion predicts the behavior of objects for which all existing forces are balanced. The first law - sometimes referred to as the law of inertia - states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s/s. Objects at equilibrium (the condition in which all forces balance) will not accelerate. According to Newton, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Newton's second law of motion can be formally stated as follows:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
