What is the mass m of a body moving with a velocity?
What is the mass m of a body moving with a velocity?
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 is an object of mass m moving with velocity v?
∴Momentum, P=mv.
What is the formula for the mass of a moving body?
Thus, the correct formula is m=m0√1−v2c2. Was this answer helpful? A famous relation in physics relates moving mass m to the rest mass m0 of a particle in terms of its speed v and the speed of light c. (This relation first arose as a consequence of special theory of relatively given by Albert Einstein).
What is mass of body and velocity?
Therefore physical quantity which is the product of mass and velocity of a body is known as momentum i.e; option C is correct.
What is the SI unit of velocity?
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 |
What is the formula for the change in velocity with mass?
According to Newton’s second law of motion, the product of the mass and rate of change of velocity is called force. Acceleration is defined as the rate of change of velocity, therefore, F=ma. Q.
How do you find the mass of an object with velocity?
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.
Does mass change with velocity?
Another result of the theory of special relativity is that as an object moves faster, its observed mass increases. This increase is negligible at everyday speeds. But as an object approaches the speed of light, its observed mass becomes infinitely large.
How does mass of a body vary with velocity?
If you increase V , the lower part will decrease in the formula which is √(1-v^2/c^2) which will increase the value of “M” so mass will increase with speed.
What is a body of mass 1 kg moving with velocity of 10m s?
Given: Mass (m)= 1 kg. Velocity (v)= 10 m/s. ∴The Kinetic Energy of the object is 50 J.
