What is the formula for relativistic mass?

  1. $m = m_0 / \sqrt{1 - v^2/c^2}$

  2. $m = m_0 \sqrt{1 - v^2/c^2}$

  3. $m = m_0 v^2/c^2$

  4. $m = m_0 c^2/v^2$


Correct Option: A
Explanation:

The formula for relativistic mass is $m = m_0 / \sqrt{1 - v^2/c^2}$, where $m_0$ is the rest mass of the object, $v$ is the velocity of the object, and $c$ is the speed of light.

What is the relationship between relativistic mass and energy?

  1. $E = mc^2$

  2. $E = m_0c^2$

  3. $E = mv^2/2$

  4. $E = mgh$


Correct Option: A
Explanation:

The relationship between relativistic mass and energy is given by the equation $E = mc^2$, where $E$ is the total energy of the object, $m$ is the relativistic mass of the object, and $c$ is the speed of light.

What is the rest mass of an object?

  1. The mass of the object when it is at rest

  2. The mass of the object when it is moving

  3. The mass of the object when it is accelerated

  4. The mass of the object when it is in free fall


Correct Option: A
Explanation:

The rest mass of an object is the mass of the object when it is at rest. It is a constant value that does not change with the velocity of the object.

What is the relativistic mass of an object?

  1. The mass of the object when it is moving

  2. The mass of the object when it is at rest

  3. The mass of the object when it is accelerated

  4. The mass of the object when it is in free fall


Correct Option: A
Explanation:

The relativistic mass of an object is the mass of the object when it is moving. It is greater than the rest mass of the object and increases as the velocity of the object increases.

What is the relationship between the relativistic mass and the velocity of an object?

  1. $m = m_0 / \sqrt{1 - v^2/c^2}$

  2. $m = m_0 \sqrt{1 - v^2/c^2}$

  3. $m = m_0 v^2/c^2$

  4. $m = m_0 c^2/v^2$


Correct Option: A
Explanation:

The relationship between the relativistic mass and the velocity of an object is given by the equation $m = m_0 / \sqrt{1 - v^2/c^2}$, where $m_0$ is the rest mass of the object, $v$ is the velocity of the object, and $c$ is the speed of light.

What is the maximum velocity that an object can reach?

  1. The speed of light

  2. The speed of sound

  3. The escape velocity

  4. The terminal velocity


Correct Option: A
Explanation:

The maximum velocity that an object can reach is the speed of light. This is because the relativistic mass of an object increases as its velocity increases, and it would require an infinite amount of energy to accelerate an object to the speed of light.

What is the energy of an object at rest?

  1. $E = m_0c^2$

  2. $E = mc^2$

  3. $E = mv^2/2$

  4. $E = mgh$


Correct Option: A
Explanation:

The energy of an object at rest is equal to its rest mass energy, which is given by the equation $E = m_0c^2$, where $m_0$ is the rest mass of the object and $c$ is the speed of light.

What is the energy of an object in motion?

  1. $E = m_0c^2$

  2. $E = mc^2$

  3. $E = mv^2/2$

  4. $E = mgh$


Correct Option: B
Explanation:

The energy of an object in motion is equal to its total energy, which is given by the equation $E = mc^2$, where $m$ is the relativistic mass of the object and $c$ is the speed of light.

What is the relationship between the energy of an object and its velocity?

  1. $E = m_0c^2$

  2. $E = mc^2$

  3. $E = mv^2/2$

  4. $E = mgh$


Correct Option: B
Explanation:

The relationship between the energy of an object and its velocity is given by the equation $E = mc^2$, where $m$ is the relativistic mass of the object and $c$ is the speed of light.

What is the mass-energy equivalence principle?

  1. Mass and energy are equivalent

  2. Mass and energy are not equivalent

  3. Mass and energy are inversely proportional

  4. Mass and energy are directly proportional


Correct Option: A
Explanation:

The mass-energy equivalence principle states that mass and energy are equivalent. This means that mass can be converted into energy and energy can be converted into mass.

What is the most famous equation in physics?

  1. $E = mc^2$

  2. $F = ma$

  3. $E = hv$

  4. $P = IV$


Correct Option: A
Explanation:

The most famous equation in physics is $E = mc^2$, which represents the mass-energy equivalence principle.

Who developed the theory of special relativity?

  1. Albert Einstein

  2. Isaac Newton

  3. James Clerk Maxwell

  4. Michael Faraday


Correct Option: A
Explanation:

Albert Einstein developed the theory of special relativity in 1905.

What is the name of the experiment that confirmed the mass-energy equivalence principle?

  1. The Michelson-Morley experiment

  2. The Davisson-Germer experiment

  3. The Stern-Gerlach experiment

  4. The Rutherford scattering experiment


Correct Option: D
Explanation:

The Rutherford scattering experiment, conducted in 1911, confirmed the mass-energy equivalence principle.
