# How do you calculate initial momentum?

## How do you calculate initial momentum?

If inelastic, then the total amount of system momentum before the collision (and after) can be determined by using the Pythagorean theorem. Since the two colliding objects travel together in the same direction after the collision, the total momentum is simply the total mass of the objects multiplied by their velocity.

How do you find the initial momentum before a collision?

Momentum calculations

1. Work out the total momentum before the event (before the collision): p = m × v.
2. Work out the total momentum after the event (after the collision):
3. Work out the total mass after the event (after the collision):
4. Work out the new velocity:

What is initial momentum in physics?

Initial momentum refers to the momentum of an object when it first starts moving.

### What is the formula P MV?

Linear momentum (momentum for brevity) is defined as the product of a system’s mass multiplied by its velocity. In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg · m/s.

How do you find initial kinetic energy?

Initial kinetic energy KE = 1/2 m1v12 + 1/2 m2v22 = joules. The following calculation expects you to enter a final velocity for mass m1 and then it calculates the final velocity of the other mass required to conserve momentum and calculates the kinetic energy either gained or lost to make possible such a collision.

How do you find initial velocity with momentum?

Finding initial velocity using conservation of momentum and energy [closed]

1. Find Normal force N=(m1+m2)g.
2. Find Ff=μN.
3. Find A: Fnet=mA.
5. Find vi: m1vi=(m1+m2)v.

## How do you find initial velocity?

How do you find initial velocity?

1. Work out which of the displacement (S), final velocity (V), acceleration (A) and time (T) you have to solve for initial velocity (U).
2. If you have V, A and T, use U = V – AT.
3. If you have S, V and T, use U = 2(S/T) – V.
4. If you have S, V and A, use U = SQRT(V2 – 2AS).

How do you find P in P MV?

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third. Along with values, enter the known units of measure for each and this calculator will convert among units.

How do you find initial and final kinetic energy?

Kinetic Energy and Work

1. The kinetic energy of an object is defined as 2 KE = 1/2 * m * v.
2. The kinetic energy of an object depends on its velocity.
3. We can this combination of force and distance work, so KE(final) – KE(initial) = Work done on object.
4. In fact, it’s a little more complicated than that.

### What is the equation used to calculate momentum?

The formula for calculating momentum is mass multiplied by velocity. An object’s momentum is equivalent to its mass times its velocity, therefore the equation for momentum is the same. Momentum is measured in kilogram-meters per second, which are all standard metric units.

How to calculate final momentum?

Steps Download Article PRO Find the mass. Mass is the amount of matter in an object. To measure the mass of an object, you can use a balance. Find the velocity. Velocity is the speed and the direction that the object travels. Right now, we will only concentrate on the speed part. Multiply the mass by the velocity. That is the momentum! The measurement for momentum is kg*m/s.

What is the formula for momentum?

The scientific formula for momentum. M x V = P Mass (m) x velocity (v) = Momentum (p) The formula for momentum is Newtons Second Law and states that mass (which means you) plus velocity equals momentum.

## What is the equation for final momentum?

The total momentum of the system is the same after the collision as before it as shown by the equation initial momentum = final momentum (where final momentum is the sum of all momentums present in the system). This principle is similar to the law of conservation of energy.
