Inertial Mass:
Inertial mass of a body refers to its resistance to acceleration when an external force is applied. It is the ratio of the external force acting on the body to the acceleration produced along a smooth horizontal surface.
Inertial mass measures a body’s ability to resist acceleration due to an external force. If two bodies experience the same force, the body with greater inertial mass will have less acceleration and vice versa.
Properties of Inertial Mass:
1. The inertial mass of a body is directly proportional to the quantity of matter it contains.
2. It is independent of the size, shape, and state of the body.
3. It is conserved in both physical and chemical processes.
4. It is unaffected by the presence of other bodies.
5. When different bodies are combined, their inertial masses add up, regardless of the materials’ nature.
6. The inertial mass of a body increases with speed. As a body with rest mass moves at higher speeds, its inertial mass increases.
Comparison between Inertial and Gravitational Masses: Similarities: 1. Both represent the quantity of matter in a body. 2. Both are equivalent in magnitude and have the same units of measurement. 3. Both are independent of the shape or state of matter. 4. Both are unaffected by the presence of otherRead more
Comparison between Inertial and Gravitational Masses:
Similarities:
1. Both represent the quantity of matter in a body.
2. Both are equivalent in magnitude and have the same units of measurement.
3. Both are independent of the shape or state of matter.
4. Both are unaffected by the presence of other bodies.
5. Both are scalar quantities.
**Differences:**
1. Inertial mass measures a body’s resistance to acceleration, while gravitational mass measures the force of attraction between the body and Earth.
2. Inertial mass is determined using Newton’s second law of motion, whereas gravitational mass is determined using Newton’s law of gravitation.
3. Inertial mass can only be measured under dynamic conditions when the body is in motion, making it less practical, whereas gravitational mass can be easily measured using a common balance.
Einstein's view of gravitation emphasizes the equivalence of gravitation and acceleration, known as the principle of equivalence. He used this principle as a foundational idea in his general theory of relativity, which explains gravitational effects as the curvature of space-time. To demonstrate theRead more
Einstein’s view of gravitation emphasizes the equivalence of gravitation and acceleration, known as the principle of equivalence. He used this principle as a foundational idea in his general theory of relativity, which explains gravitational effects as the curvature of space-time.
To demonstrate the equivalence of inertial and gravitational masses, Einstein proposed a simple thought experiment. Imagine a person inside a small box, known as the “Einstein box,” which is at rest on Earth’s surface and subject only to gravity. In another scenario, the box accelerates through interstellar space at 9.8 m/s², with an external force causing this acceleration.
In both situations, the person inside the box cannot distinguish between the two by conducting experiments within the box. For example, the platform scale on which the person stands reads the same weight in both cases. Additionally, if the person observes an object falling past them, it accelerates at the same rate in both situations. This demonstrates the equivalence of inertial and gravitational masses.
