The heisenberg uncertainty principle is what you are thinking of. However, the relation you asked about does not exist. Most formalisms claim it as (uncertainty of position)(uncertainty of momentum) >= hbar/2.
There is a somewhat more obscure and less useful relation (uncertainty of time)(uncertainty of energy) >= hbar/2. But in this relation the term of uncertainty of time is not so straightforward (but it does have an interesting meaning).

Heisenberg's Uncertainity Principle states that you cannot simultaneously know both of?
The position and the momentum of a particle
What are the two parts of the Heisenberg uncertainty principle?
Heisenberg uncertainty principle states that , the momentum and the position of a particle cannot be measured accurately and simultaneously. If you get the position absolutely correct then the momentum can not be exact and vice versa.
What is important about the uncertainty principle?
Heisenberg's Uncertainty Principle is the principle that states that the momentum and the position of a quantum particle can not be simultaneously accurately known. This means that the more precisely you know the momentum, the less you know about the position and vice-versa.
Which of newtons law states that the velocity or speed of an object does not change unlewhich of newtons law states that the velocity or speed of an object does not change unless a force interferes?
That is Newton's First Law.
Which model of light states that light is composed of millions of particals?
Particle model
According to the heisenberg uncertainty principle if the position of a moving particle is known what other cannot be known?
According to the Heisenberg uncertainty principle if the position of a moving particle is known velocity is the other quantity that cannot be known. Heisenberg uncertainty principle states that the impossibility of knowing both velocity and position of a moving particle at the same time.

A net force acts on a particle this net force is not equal to zero is this sufficient information to conclude that the speed of the particle changes?
Yes, one of Newtons Laws (I've forgotten which one) states that F=ma, which can also be written a=F/m. As long as F (the net force) is not zero, the particle will experience acceleration, and hence, a change in its velocity.
What is Heisenberg's uncertanity principle?
Heisenberg's uncertainty principle concerns electron momentum and position.It states that for any moving particle, its position and its momentum cannot be determined at a same time.Mathematically, the product (dx)(dp) is greater than or equal to h/4(pi)dx = uncertainty in positiondp = uncertainty in momentumh = Planck's constant (6.620 x 10-34 J.s)
How is velocity same from instantaneous speed?
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
What is necessary to accurately and completely describe the motion of an object?
To completely describe the motion of an object you will need to know (1) the object's position in space and time, (2) the objects velocity, including the direction of travel, and (3) the object's acceleration, including the direction of acceleration. However, the Heisenburg Uncertainty principle states that the more accurately you measure object's position, the less information you will have about its velocity, and vica versa. The more accurately you measure an object's velocity, the less information you will have about its position.
What does particle mean in science?
Particle model is a scientific model of the 3 states of matter: solids, liquids, and gases.

What momentum and position can't be measured at the same time?
The position and momentum of any sub-atomic particle cannot be measured at the same time due to the Heisenberg uncertainty principle. Simply put, it states that the more we know about one of the two properties, the less we know about the other.
Do velocity describe both speed and time?
No. Velocity states both speed and direction.Time gets involved in calculating the speed.
