Thermal Capacity Thermal Capacity of a substance is defined as the amount of heat required to change its temperature through one degree. If Q is the amount of required to change the temperature of a body of mass m through, then Q = msΔθ If temperature difference = 1, then Q = ms The value Read more about Thermal Capacity[…]
Collision between Bullet and Vertically suspended block A collision is said to have taken place if two bodies interact with each other and undergo a change in momentum and or kinetic energy. A bullet of mass m is fired horizontally with velocity u in block of mass M suspended by vertical thread. After the collision Read more about Collision between Bullet and Vertically suspended block[…]
Relation between Volumetric Strain, Lateral Strain and Poisson’s Ratio If the deforming force produces a change in volume along the strain produced in the body is called Volumetric Strain, the ratio of the change in radius or diameter to the original radius or diameter is called Lateral Strain, the ratio of lateral strain to longitudinal Read more about Relation between Volumetric Strain, Lateral Strain and Poisson’s Ratio[…]
The coefficient of friction is a number which represents the friction between two surfaces. Between two equal surfaces, the coefficient of friction will be the same. The symbol usually used for the coefficient of friction is μ. A body slides on a smooth wedge of angle θ and its time of descents is t. if Read more about Coefficient of Friction between a Body and Wedge[…]
Acceleration of Block against Friction Newton’s second law says that the acceleration (a) of an object is proportional to the force (F) applied on it, and the proportionality factor is the object’s mass (m). Force is a vector quantity, which means we must consider the direction in which it acts. Two main types of frictional Read more about Acceleration of Block against Friction[…]
Stopping of Two Blocks due to Friction Friction is an opposing force that opposes the motion of one body over the surface of another body. Like in case of a ball freely rolling on the ground, the ball eventually comes to stop, because of the force of friction that acts between ball and the ground. Read more about Stopping of Two Blocks due to Friction[…]
Motion of two bodies one resting on the other – 2nd Condition When a body A of mass m is resting on a body B of mass M then two conditions are possible: 2) A force F is applied to the lower body and then following four situations are possible i) When there is no Read more about Motion of two bodies one resting on the other – 2nd Condition[…]
When a body A of mass m is resting on a body B of mass M then two conditions are possible: 1) A force F is applied to the upper body, and then following four situations are possible: (a) The body A will move on body B with acceleration (F/m): . (b) The body B Read more about Motion of two bodies one resting on the other[…]
The physical quantities may be broadly classified into the vectors and the scalars. The quantities with magnitude and direction both are known as vector quantities, it means a vector is a physical quantity that has both magnitude and direction. If two non-zero vectors are represented by the two sides of a triangle taken in same Read more about Triangle Law of Vector Addition of Two Vectors[…]
Cylindrical Capacitor A cylindrical capacitor consists of two coaxial cylinders of radii a and b, say b > a. The outer one is earthed. The cylinders are long enough so that we can neglect fringing of electric fields at the ends. The electric field at a point between the cylinders will be radial, and its Read more about Cylindrical Capacitor[…]
