Is it true that when a constant force is applied to a body it moves a uniform acceleration?

Yes, that is true - assuming you are referring to the net force, i.e., the sum of all forces on an object. Please note that in practice, opposing forces such as air resistance may vary depending on speed.

If a body is acted by a constant force the body will have uniform?
"acceleration"
When constant force is applied to a body then it does it moves with uniform speed?
velocity
Plot the graph of force vs acceleration?
Acceleration is directly proportional to applied force. When acceleration increases, force also increases. If the force is tripled, the acceleration will also be tripled. Note that the mass must remain constant...
A body is in equilibrium when it's?
when it is at rest, or in constant uniform motion with net force and moment of zero (no acceleration)
A body falling freely from a hight towards the earth moves with uniform?
It moves with uniform acceleration,because it has a constant force acting on it (its weight).
What will the mass and acceleration produce if the applied force is constant?
If the applied force is constant, the acceleration will also be constant. To know the actual amount of acceleration, you divide the force by the mass.
Does the acceleration remain constant if the applied force was increasing?
No. Acceleration is proportional to the applied force.
If a body is acted by a constant force the body will have uniform?
"acceleration"
What is Newton's 2nd law?
Newtons second law states that the acceleration of a body is proportional to the force applied to it.
When constant force is applied to a body then it does it moves with uniform speed?
velocity
Is centripetal acceleration a uniform acceleration give reason?
No it is not because its direction is constantly changing. It is not a constant force. Force has direction as well as magintude and while it magnitude is constant its direction is not.
Why does a body need uniform acceleration?
From a kinematic perspective, whenever an object's velocity changes at a constant rate it is in uniform acceleration.From a dynamic perspective, whenever the net force on an object is constant the object will undergo uniform acceleration.
When will you say a body is in uniform acceleration and non-acceleration?
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.
Is second equation of motion valid for non uniform acceleration?
Yes. It just has to be remembered that the equation is describing a balance betweena force and the increment of momentum of the system per time unit on which the force is being applied "at a given instant t".For a given system with constant mass m, we can write Newton's 2nd law of motionas:F(t) = m∙a(t)where force F(t) and acceleration a(t) are a function of time (notice that if the forceis constant during time applied, acceleration results constant or uniform).If you know how the force is varying in time (function F(t)), then you know thefunction of acceleration in time: a(t) = F(t)/m
How are constant force is related to mass and acceleration?
Force = (mass) times (acceleration) Constant force produces constant acceleration.
What happens to the acceleration if the force applied is increased three times?
Assuming the mass remains constant, the acceleration will be tripled as well.
Plot the graph of force vs acceleration?
Acceleration is directly proportional to applied force. When acceleration increases, force also increases. If the force is tripled, the acceleration will also be tripled. Note that the mass must remain constant...
