How to find velocity with only mass and momentum? (2024)

How to find velocity with only mass and momentum?

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.

How do you find velocity with only mass?

To calculate velocity from mass, you must know the value of the momentum since momentum is what relative velocity and mass together. Once you know the momentum, simply divide by the mass to get the velocity.

How to 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.

How do you find speed without time?

How do you calculate average speed without time? yes, you can. If a certain distance is covered at x km/hr and the same distance is covered by y km/hr then the average speed during the whole journey is 2xy/x+y km/hr.

What are the 3 formulas for velocity?

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

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.

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.

What is the formula for momentum with initial and final velocity?

The Impulse-Momentum Principle says I=mv−mu I = m v − m u which is final momentum - initial momentum so Impulse is the change in momentum. The principle of states that total momentum before impact is equal to total momentum after impact, m1u1+m2u2=m1v1+m2v2.

What are the 5 equations of velocity?

The equations are as follows: v=u+at,s=(u+v2)t,v2=u2+2as,s=ut+12at2,s=vt−12at2.

How to find velocity with only mass and momentum? (2024)

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.

Does velocity mean speed?

Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

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.

What is the formula for velocity example?

Equation for Velocity

To figure out velocity, you divide the distance by the time it takes to travel that same distance, then you add your direction to it. For example, if you traveled 50 miles in 1 hour going west, then your velocity would be 50 miles/1 hour westwards, or 50 mph westwards.

How do you calculate momentum?

Step 1: List the mass and velocity of the object. Step 2: Convert any values into SI units (kg, m, s). Step 3: Multiply the mass and velocity of the object together to get the momentum of the object.

How do you calculate speed and velocity?

The formula for speed is change in distance divided by change in time. The formula for velocity is change in displacement divided by change in time.

What does S stand for in physics?

Distance in physics is understood as the speed of an object multiplied by the total time taken by the object to travel the length of its path. When calculating the distance formula, "d" represents distance, "s" represents speed, and "t" represents time.

What is velocity explained simply?

Velocity is defined as a vector measurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.

What is velocity and example?

In simple words, velocity is the speed at which something moves in a particular direction. For example as the speed of a car travelling north on a highway, or the speed a rocket travels after launching.

How far did the rock fall for 1.43 seconds?

The correct answer is indeed 10.02 meters.

Can a body have energy without momentum?

A body can have energy without having momentum if it possess potential energy but if body possess momentum then it must posses kinetic energy. Momentum and energy have different dimensions.

How do you calculate mass?

The first formula of mass is expressed as, Mass = Density × Volume. This means if we know the density and volume of an object, we can find its mass using this formula of mass. The second formula of mass is expressed as, Mass = Force ÷ Acceleration.

When momentum of a body increases by 100?

Therefore percentage increase in kinetic energy, = (4ρ22m - ρ22m} / {ρ22m} = 300%
