What is the moment of an object of mass m moving with velocity v?
What is the moment of an object of mass m moving with velocity v?
The momentum, p of an object is defined as the product of its mass, m and velocity, V. Momentum = Mass x Velocity. That is, p = mv.
What is the mass at velocity V?
The mass m of a body moving with a velocity v is given by m=m0√1−v2c2 where m0 = rest mass of body =10kg and c = speed of light =3×108m/s.
What will be the momentum of a body of mass m which is moving with a velocity v?
P = M × V.
What do we get by the product of mass and velocity?
The product of mass and velocity is called momentum. The SI unit of momentum is kgms−1.
What is the formula for moment mass and velocity?
p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.
What is the formula for velocity with 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 happens as V → c −?
As v → c − It means that the velocity of the particle approaches the speed of light or gets close to the speed of light but is less than the speed of light.
What is the SI unit for mass velocity?
The S.I. unit for Mass Velocity is Kilogram per Second per Square Meter (kg/s/m²).
What are the SI units for velocity?
Therefore, velocity is expressed in metres/second or m/s. The SI unit of velocity is metre per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).
What is SI unit of momentum?
| Momentum | |
|---|---|
| SI unit | kilogram meter per second (kg⋅m/s) |
| Common symbols | p, p |
| Other units | slug⋅ft/s |
| Dimension | MLT−1 |
Does momentum depend on mass and 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.
What is the momentum of a man of mass 75 kg?
The momentum of a man of mass 75 kg when he walks with a uniform velocity of 2m/s. We have to find momentum of that man. Thus, momentum of a man is 150 kg. m/s.
What is the formula for the mass moment?
The formula for the moment of inertia is the “sum of the product of mass” of each particle with the “square of its distance from the axis of the rotation”. The formula of Moment of Inertia is expressed as I = Σ miri2.
What is an object of mass m moving with constant velocity v has a net force on it equal to?
Answer and Explanation: If the velocity is not changing then the acceleration is zero. Thus the net force on the object is zero. The answer is (d) 0.
What is the mass of an object moving with velocity V in Einstein’s theory of special relativity?
In Einstein’s theory of special relativity, the mass m of an object moving with velocity v is m = (m0 )/(\squareroot 1-(v)^2/(c)^2) where m0 is the mass of the object when at rest and c is the speed of light.
What is the momentum of a body of mass 2m and velocity v 2?
Given: Mass of the body, m = 2m, Velocity of the body, v = v/2. Therefore, the momentum of the body is mv.
