How to calculate velocity using momentum and mass? (2024)

How to calculate velocity using momentum and mass?

You can rearrange the equation to calculate velocity if you know momentum and mass, Velocity = Momentum/Mass, or to calculate mass if you know momentum and velocity, Mass = Momentum/Velocity.

How do you find velocity with mass and momentum?

So, you divide momentum by mass in order to find speed, or velocity using the momentum equation.

How do you calculate velocity?

Determine the object's original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

What is the velocity of an object that has momentum?

In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object's mass and also its velocity. Thus the greater an object's mass or the greater its velocity, the greater its momentum. Momentum p is a vector having the same direction as the velocity v.

What will be the velocity if the momentum becomes 200ns?

Expert-Verified Answer

what will be the velocity if the momentum becomes 200 Ns​, given the mass of the object is m kg. Let us suppose the mass (m)of the object is 2kg. The momentum of the object is the product of mass and velocity. Hence, the velocity of the object would be 100m/s.

How do you find final velocity with momentum?

If you know an object's initial momentum and the force applied to it over a certain period of time, you can calculate its final momentum using the formula: Final Momentum = Initial Momentum + (Force x Time) Then, you can calculate the final velocity by dividing the final momentum by the object's mass: Final Velocity = ...

What are the 3 formulas for velocity?

The three equations are,
  • v = u + at.
  • v² = u² + 2as.
  • s = ut + ½at²

What are the two formulas for velocity?

Equations of Motion
VariableEquation
Velocityv=u+at
Displacement with positive accelerations=ut+21at2
Displacement knowing initial and final velocitiess=21(u+v)t
Velocity squaredv2=u2+2as

Is momentum related to velocity?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

Is momentum just velocity?

In Newtonian mechanics, momentum ( pl. : momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.

What is the formula for velocity in impulse and momentum?

Momentum and Impulse

The momentum, p , of a body of mass m which is moving with a velocity v is p=m×v=mv p = m × v = m v .

How do you find initial velocity from momentum?

Answer and Explanation:

Initial momentum uses the equation: mass (m) multiplied by velocity (v) equals momentum (p). The equation looks like "p = m x v." Momentum is the amount of movement an object has based on how much mass it has and how fast it is moving in one direction.

How do you calculate velocity from mass and impulse?

By using momentum change: The formula to calculate impulse through momentum change is by calculating the mass of the body and the velocity. In this case, Impulse will be equal to the product of mass and velocity. So J= m*v. Here v will be calculated by subtracting the final velocity from the initial velocity.

How do you calculate momentum examples?

Example: What is the momentum of a 1500 kg car going at highway speed of 28 m/s (about 100 km/h or 60 mph)?
  1. p = m v.
  2. p = 1500 kg × 28 m/s.
  3. p = 42,000 kg m/s.

Can you find momentum without velocity?

Flexi Says: Momentum cannot be found without velocity because momentum is a product of mass and velocity. The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity. Without knowing the velocity, you cannot calculate momentum.

What is the formula for velocity vs mass?

Mass is measured in (kg), and velocity is measured in meters per second (m/s). The SI unit for momentum is kg • m/s. You can rearrange the equation to calculate velocity if you know momentum and mass, Velocity = Momentum/Mass, or to calculate mass if you know momentum and velocity, Mass = Momentum/Velocity.

What are 5 examples of velocity?

The applications of velocity are illustrated by the examples below:
  • Earth's rotation around the Sun,
  • Moon's orbital motion around the Earth.
  • The vehicle's speed.
  • How quickly the train is moving.
  • The river is moving at a fluctuating speed.
  • The rate at which water leaves a faucet.
  • The speed at which a bat strikes a ball.

What is a velocity short answer?

The velocity of an object is the rate of change of its position with respect to a frames of reference and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion (e.g. 60 km/hr to the north).

Can displacement be negative?

Displacement can be positive, negative or zero.

Can acceleration be negative in physics?

So, negative acceleration means acceleration in the negative direction of the reference frame. Negative acceleration decreases the velocity or speed of an object in motion depending upon the direction of the object's motion. Negative acceleration is also termed as retardation.

What does S stand for in physics?

second (s) four-velocity. meter per second (m/s) potential energy. joule (J)

Is weight another form of gravity?

Weight is the force of gravity on an object. Mass always stays the same, but weight can change depending on how much gravity is acting upon an object. Cool fact: Any two masses have a gravitational attraction for one another, and the greater the mass, the greater the pull.

What is momentum for dummies?

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 does force equal?

Force Equals Mass Times Acceleration: Newton's Second Law.

Is force a vector?

Forces as a vector

A force applied to a particle is also a vector as it has both a magnitude and a direction. We can use the formula F=ma F = m a , where m is the mass of the particle, to solve problems about force.
