Topic 3 Waves - Physics Resources

Total Internal Reflection: Consider a ray of light passing from glass to air. If the ray is along the normal then it will not refract. When the angle of incidence is small; we get a weak internally reflected ray (light grey) and strong refracted ray (dark grey). As we increase the angle of incidence, the angle of refraction also increases.

Topic 2 Thermal Physics - Physics Resources

Matter is made up of atoms and molecules, which may only be seen by electronic microscope. Kinetic Molecular Theory of Matter: The kinetic molecular theory explains the forces between molecules and the energy that they possess. This theory has 3 basic assumptions. 1. Matter is made up of tiny small particles (atoms, molecules or ions).

14. An object with a mass M is suspended from an elastic spring with a spring constant k. The object oscillates with period T on the surface of Earth. If the oscillating system is moved to the surface of Moon, how it will change the period of oscillations? Acceleration due to gravity on moon= 1.6 m/s 2 A. The period is increased by factor √6 B.

and physics of the simple pendulum. Waves in elastic media are intimately connected with harmonic oscillations. (Stretched strings, coiled springs, air, etc., are examples of elastic media). We shall illustrate this connection through simple examples. Consider a collection of springs connected to one another as shown in Fig. 15.1. If the spring

Collisions - Boston University

DEFINITIONS Elastic collision Inelastic collision Completely inelastic collision However, the kinetic energy is not necessarily conserved. There are four possible cases. 4 A ballistic pendulum A ballistic pendulum is a device used to measure the speed of a bullet. A bullet of mass m = 50g is fired at a block of wood (mass M = 750 g) hanging ...

Hooke’s law in terms of stress and strain is

Physical Pendulum. Instead of a point mass, the vibrating object has size. The period is mgd I T 2S where d is the distance from the rotation axis to the center of mass of the object and I is the rotational inertia about the rotation axis (not the center of mass). Damped Oscillations In reality a vibrating system will stop vibrating.

Mechanical Engineering Interview Questions and Answers

The longer the pendulum is the greater the period of each swing. If you increase the length four times, you will double the period. It is hard to notice, but the period of a pendulum does depend on the angle of oscillation. For small angles, the period is constant and depends only on the length of the pendulum.
