Determination of Young’s modulus with vernier method

Determination of Young's modulus with vernier method. To determine Young's Modulus for copper, two pieces of copper wire seven or eight metres in length are hung from the same support one wire carries a scale of millimetres fixed to it so that the length of the scale is parallel to the wire. A vernier is fixed…

Comparison of masses of two substances using spring balance

Comparison of masses of two substances using spring balance. Mass is the quantity of matter in a body.  More specifically, it is the measurement of the inertia or sluggishness that a body, in the absence of friction, exhibits in response to any effort made to start it, stop it, or change in any way from its…

Determination of the Spring Constant of a Spring

Determination of the Spring Constant of a Spring. Any physicist knows that if an object applies a force to a spring, then the spring applies an equal and opposite force to the object. Hooke’s law gives the force a spring exerts on an object attached to it with the following equation: F = –kx where the minus…

Determine the radius of curvature of a convex or concave spherical surface by spherometer

Determine the radius of curvature of a convex or concave spherical surface by spherometer Radius of curvature: The distance from the center of a circle or sphere to its surface is its radius. For other curved lines or surfaces, the radius of curvature at a given point is the radius of a circle that mathematically…

Verification of the laws of Galileo’s falling body

Verification of the laws of Galileo's falling body. Falling Bodies, objects moving downward under the influence of gravity. The nature of this motion is the same for an object that falls straight down as it is for one that moves forward and down at the same time. Thus a bullet fired horizontally from a rifle falls…

Determine the Potentiel energy of a spring

Determine the Potentiel energy of a spring( English Version). In physics, you can examine how much potential and kinetic energy is stored in a spring when you compress or stretch it. The work you do compressing or stretching the spring must go into the energy stored in the spring. That energy is called elastic potential energy…
