Gravitational Force – Weakest force; but has infinite range. (Not part of the standard model) Weak Nuclear Force – Next weakest; but short range. Electromagnetic Force – Stronger, with infinite range. Strong Nuclear Force – Strongest; but short range. Gravitational Force The gravitational force is weak but very long-ranged. Furthermore, it is always attractive. It acts between any two pieces of matter in the Universe since mass is its source. Weak Nuclear Force The weak force is responsible for radioactive decay and neutrino interactions. It has a very short range and. As its name indicates, it is very weak. The weak force causes Beta-decay ie. the conversion of a neutron into a proton, an electron and an antineutrino. Electromagnetic Force The electromagnetic force causes electric and magnetic effects such as the repulsion between like electrical charges or the interaction of bar magnets. It is long-ranged but much weaker than the strong force. It can be attractive or repulsive and acts only between pieces of matter carrying an electrical charge. Electricity, magnetism, and light are all produced by this force. Strong Nuclear Force The strong interaction is very strong but very short-ranged. It is responsible for holding the nuclei of atoms together. It is basically attractive but can be effectively repulsive in some circumstances. The strong force is ‘carried’ by particles called gluons; that is, when two particles interact through the strong force, they do so by exchanging gluons. Thus, the quarks inside of the protons and neutrons are bound together by the exchange of the strong nuclear force.

The potential difference is the work done per unit charge.
The dimensional formula for potential difference is dimension of work/dimension of charge =dimensions of mass times acceleration times distance/ dimension for charge ={tex}M^1L^1T^-2L^1 / A^1T^1 = M^1 L^2 T^-3A^-1 {/tex}

The range of variation over the seven days of observation is 162 s for clock 1, and 31 s for clock 2. the average reading of clock 1 is much closer to the standard time than the average reading of clock 2. The important point is that a clock's zero error is not as significant for precision work as its variation, because a 'zero-error' can always be easily corrected. Hence closk 2 is to be preferred to clock 1.

Zero acceleration

Yogita Ingle 4 years, 2 months ago

Acceleration is the rate of change in velocity expressed mathematically as dv/dt ​ = a. An object moving at uniform or constant velocity has zero acceleration.

Scientific method involves making observations, forming questions, making hypotheses, doing an experiment, analyzing the data, and forming a conclusion. Every scientific experiment performed is an example of the scientific method in action, but it is also used by non-scientists in everyday situations.The scientific method consists of six steps:

  • Define purpose.
  • Construct hypothesis.
  • Test the hypothesis and collect data.
  • Analyze data.
  • Draw conclusion.
  • Communicate results.

Ampere is the SI unit of current.

Yogita Ingle 4 years, 2 months ago

SI unit of current is ampere.
1 ampere is the constant current that will produce an attractive force of 2 × 107 Newton per meter of length between two straight, parallel conductors of infinite length and negligible circular cross section placed one meter apart in a vacuum.

Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. ... For example, when a pendulum swings upward, kinetic energy is converted to potential energy. Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.
