Newton's laws of motion (Sir I. Newton)
Newton's first law of motion
A body remain continues in its state of constant velocity (that may be zero) unless it is acted on by an external force.
Newton's second law of motion
For unbalanced force working on a body, the acceleration generated is proportional to the force impressed; the constant of proportionality refer to the inertial mass of the body.
Newton's third law of motion
In any system where no external forces are exist; every action force is opposed by an equal and opposite reaction force always.
#question. A child applies a force F? parallel to the x-axis to a 10.0-kg sled moving on the frozen surface of a small pond. As the child controls the speed of the sled, the x-comp
What is electric flux? Write its S.I. units. Using Gauss's theorem, assume an expression for the electric field at a point because of a uniformly charged infinite plane sheet.
Uses of radio isotopes: Used in i)Medicine ii) Industry iii) Agriculture iv) Meteorology and v) Radio active dating.
What occurs if electrical connection or electrical joint is loose? Ans: Because of loose connection at joints resistance at that point will increase thereby the I²R loses ar
Potential difference: When charges move from one point to another, it is not the actual values of potential at those points which are Important, but the potential different (pd
A 15-kg child experiences an acceleration of 0.25 m/s2 as she is pulled 1.7 m horizontally across the floor by her sister. Calculate the change in the child's kinetic energy.
1 Coulumb Charges: 1 coulumb charge is that amount of charge which when placed 1 m from an identical charge in vacuum which repels it with a force of 8.99 × 109 N.
