The specific latent heat of fusion, Lf , is defined as the amount of heat required per unit mass to change a substance from the solid phase to the liquid phase without any change in temperature. Newton’s second law states that the rate of change of momentum of a body is proportional to the resultant force acting on it and the change takes place in the direction of the force. The frequency f of an object in circular motion is the number of complete revolutions made by the object per unit time.Waves:Displacement is the distance moved by the particle from its equilibrium position. 0000014899 00000 n Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. Heat is the non-mechanical transfer of energy from the environment to the system or from the system to the environment because of a temperature difference between the two. Stability of an object refers to its ability to return to its original position after it has been displaced from that position.

Google+. Newton’s first law of motion states that a body will continue in its state of rest or uniform motion in a straight line unless an external resultant force acts on it. Frequency f of a periodic motion is the number of cycles per unit time. The moment of a force is the product of the force and the perpendicular distance between the axis of rotation and the line of action of the force. This physics textbook is designed to support my personal teaching activities at Duke University, in particular teaching its Physics 141/142, 151/152, or 161/162 series (Introduc-tory Physics for life science majors, engineers, or potential physics majors, respectively). Hooke’s Law states that within the limit of proportionality, the extension produced in a material is directly proportional to the load applied. Intensity of a wave is the rate of transfer of energy per unit area perpendicular to the direction of travel of the wave.Oscillations:Periodic motion is the regular, repetitive motion of a body which continually retraces its path at regular intervals. This would help in proper revision and a quick glance whenever required.
