What is the energy–momentum relation in physics?
In physics, the energy–momentum relation, or relativistic dispersion relation, is the relativistic equation relating total energy (which is also called relativistic energy) to invariant mass (which is also called rest mass) and momentum. It is the extension of mass–energy equivalence for bodies or systems with non-zero momentum.
What is the direction of momentum?
He is the co-author of "String Theory for Dummies." Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object's motion.
What is the formula for momentum in physics?
p = momentum. m = mass. v = velocity. The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v).
What is the variable used to represent momentum?
The variable used to represent momentum is p. The equation to calculate momentum is shown below. The SI units of momentum are kilograms times meters per second, or kg * m / s . As a vector quantity, momentum can be broken down into component vectors.
What is momentum triangle?
The equation for momentum is: p = mv. In a triangle equation, you cover the variable that you want to solve, and the other two line up like they are in the correct equation. This equation is sometimes called a 'triangle equation.
What is the formula for momentum triangle?
The Impulse Momentum Calculator uses the formula FΔt = mΔv, or force F multiplied by the change in time Δt equals mass m times the change in velocity Δv.
What does momentum explain?
Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving.
What is the momentum symbol called?
symbol pMomentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p. Where m is the mass and v is the velocity.

Why is P symbol for momentum?
Choosing “I” as its symbol would lead to confusion with moment of inertia and inertia. For this reason the Germans and French chose “p” for momentum.
Who invented momentum?
At this point, we introduce some further concepts that will prove useful in describing motion. The first of these, momentum, was actually introduced by the French scientist and philosopher Descartes before Newton.
Is momentum a force?
Even though these physical quantities look alike, there is a difference between force and momentum. Force is generally the external action upon a body, whether a pulling or pushing action. Momentum, on the other hand, is the representation of the amount of motion within a moving body.
What is the formula for conservation of momentum?
p=p′Equation of Conservation of Momentum The equation describing the Law of Conservation of Momentum is p=p′ , where p is the system's initial momentum and p′ is the system's final momentum. This equation can be expanded using the definition of momentum into m1v1+m2v2=m1v′1+m2v′2 m 1 v 1 + m 2 v 2 = m 1 v 1 ′ + m 2 v 2 ′ .

This is also the essence of the meaning in physics, though in physics we need to be much more precise. Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol . Where is the mass and is the velocity.
What are momentum and impulse?
Learn what momentum and impulse are, as well as how they are related to force.
How many s is the specific impulse of the jet engines?
Exercise 1b: The specific impulse of the jet engines is known to be around 6000 s. How many kilograms of fuel were burned in getting the aircraft up to take-off speed?
Why is impulse important?
One of the reasons why impulse is important and useful is that in the real world, forces are often not constant. Forces due to things like people and engines tend to build up from zero over time and may vary depending on many factors. Working out the overall effect of all these forces directly would be quite difficult.
What is specific impulse?
Specific impulse is impulse measured relative to the weight of fuel—on earth—used to produce the impulse. Because we are dividing an impulse by a force—the force on the fuel due to earth's gravity—the force units cancel out, and the units for specific impulse are simply seconds. A rocket might have a specific impulse of 300 s.
Why is area important in a force time curve?
This is equivalent to finding the area under a force-time curve. This is useful because the area can just as easily be found for a complicated shape—variable force— as for a simple rectangle—constant force. It is only the overall net impulse that matters for understanding the motion of an object following an impulse.
Is momentum a vector quantity?
The standard units for momentum are , and momentum is always a vector quantity. This simple relationship means that doubling either the mass or velocity of an object will simply double the momentum. The useful thing about momentum is its relationship to force.

Is the time rate of change of the total momentum of the system of objects zero?from universalclass.com
In other words, the time rate of change of the total momentum of the system of objects is zero in this case; this is simply a statement of the law of conservation of linear momentum for a closed and isolated system. That is to say, the total momentum is constant for a given system of objects on which no external force acts. This conclusion is extremely useful for problems involving, for instance, collisions of objects. The following practice problems allow you to explore the implications of this result.
