Just use Newton's Second Law. That is, divide the force by the acceleration.

What is the effect of acceleration on an object which is not moving?
An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
What is the net force when the object encounters 15-N of air resistance?
if its in freefall, constant force down = mass (kg) * gravitational acceleration (about 9.8 on earth), so 100 kg body gives 100 * 9.8 = 98 newtons, subtract your 7 n = 91 n for acceleration .
What gives an object inertia for newtons laws?
Nothing gives an object inertia. Inertia is not a force. It is just the tendency of an object to continue in its motion if there is no force acting upon it.
Acceleleration is directly proportional to force but inversely proportional to mass what does this mean?
It means that if you increase the force, acceleration will increase. However, if you increase the mass of the object you are accelerating, the acceleration will decrease. It all stems from the basic equation F=ma, where F is the force, m is the mass and a is the acceleration. Rearranging for a gives a=F/m. This means that as m is the denominator, if it doubles and F remains constant, a will halve.
If a net force of 120N gives an object an acceleration of 1.5 m s s what is the mass of the object?
Force is equal to the acceleration times mass. So, 120 N = 1.5 ((m/s)/s) times mass. So, the mass is 80 kg.
Does a change in force acting on an object change that object's acceleration?
F = ma (force equal mass times acceleration) Therefore a = F/m So acceleration changes in direct proportion to the change in force. Half the force gives half the acceleration.
Force can also be referred to as the weight of an object?
Yes, the acceleration of gravity times the mass of the object gives a force that is the weight.
Why are the objects easier to push or pull than others?
An object with a greater mass needs more force. Mass is what gives an object resistance to acceleration. Newton's Third Law: force = mass x acceleration, or acceleration = force / mass.
An unbalanced force of 30 N gives an object an acceleration of 5. What force would be needed to give it an acceleration of 1?
If a force of 30 N imparts an acceleration of 5 to an object and we desire only one fifth of that acceleration, then we apply only one fifth of that force. Take the 30 N and divide it by 5 and we find that 6 N is the force required to give our test object an acceleration of 1.
What is the effect of acceleration on an object which is not moving?
An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
How does the direction of acceleration compare with the direction of the net force that produces it?
Acceleration is proportional to net force.That means that acceleration is equal to (net force) times (something).The 'something' is [ 1 / (the mass of the object being accelerated by the force) ].
What is the relation ship between acceleration and the second law of motion?
Newtons second law tells us that acceleration is produced when a force acts on a mass. The greater the mass (object being accelerated) the greater the amount of force needed (to accelerate the object). This law gives the exact relationship between force, mass, acceleration. This can be expressed as the mathematical equation F= M x A or Force = Mass x Acceleration
What is the force exerted on objects by the earths pull?
There is both gravitational and magnetic force associated with the earth. The mass of the earth gives rise to gravity, and magneto action in the core generates the magnetic field that moves compass needles.
What do unbalanced forces cause a change in?
If a force is unbalanced, it will cause an acceleration upon the object which it is acting. The magnitude of this acceleration can be calculated by dividing the Net Resultant Force by the mass of the object. This comes from Newton's Second Law of Motion, which gives us the equation F=ma, which can be rearranged into F/m=a.
If the force acting upon an object is increased what happens to the objects acceleration?
its acceleration will be increased
What is the net force when the object encounters 15-N of air resistance?
if its in freefall, constant force down = mass (kg) * gravitational acceleration (about 9.8 on earth), so 100 kg body gives 100 * 9.8 = 98 newtons, subtract your 7 n = 91 n for acceleration .
What are the differences in newtons laws?
The first one sets the system of coordinates (inertial). The second one gives connection between the net force and the acceleration. The third one postulates than if a first object applies some force F to a second object. The second object is applying the same force F to the first object.
