Pulley A single fixed pulley changes the direction of force only and in general assumed to be massless and frictionless. It is clear from the example given below. Ex. A bucket of mass $25 \mathrm{~kg}$ is raised by a $50 \mathrm{~kg}$ man in two different ways as shown in fig. What is the action on the floor by the man in the two cases? If the floor yields to a normal force of 700 N, which mode should the man adopt to lift the bucket without the floor yielding? Sol. Here, mass of the bucket, $m=...

Read More →What is Motion of Bodies in Contact ?
Motion of Bodies in Contact (a) When two bodies of masses $m_{1}$ and $m_{2}$ are kept on the frictionless surface and a force $F$ is applied on one body, then the force with which one body presses the other at the point of contact is called Force of Contact. These two bodies will move with same acceleration $=\mathrm{a}$. When the force $F$ acts on the body with mass $m_{1}$ as shown in fig. (1) and (1a) $F=\left(m_{1}+m_{2}\right)$ a. If the force exerted by $m_{2}$ on $m_{1}$ is $f_{1}$ (forc...
Read More →What is Force?
Force A force is a push or a pull. [1] Since push or a pull has both magnitude and direction, so that force is a vector quantity. [2] Forces occur in pairs. If object $A$ exerts a force on object $B$, then $B$ also exerts a force on $A$. For example, when a bat strikes a ball the bat exerts a force on the ball, but the ball exerts a force on the bat also. [3] A force can cause an object to accelerate. If you kick a foot ball the ball's velocity changes while your foot is in contact with it. [4] ...
Read More →What is Mass?
MASS The mass of an object is a measure of the object's resistance to a change in its velocity. A child's wagon, coasting along a horizontal sidewalk, is more difficult to stop when it is loaded with bricks than when it is empty. The system, wagon plus load, is more massive in the former case than in the latter. Mass is a scalar quantity and is additive. That is, if we fasten two objects of mass $m_{1}$ and $m_{2}$ together, then the mass $m_{12}$ of the composite system is $m_{12}=m_{1}+m_{2}$ ...
Read More →What is Newton's third Law of Motion?
Newton's third Law of Motion To every action there is always equal and opposite reaction or the mutual actions of two bodies upon each other are always directed to contrary parts. The first and second laws are statements about a single object, whereas the third law is a statement about two objects. [A] According to this law, every action has equal and opposite reaction. Action and reaction act on different bodies and they are simultaneous. There can be no reaction without action. [B] If an objec...
Read More →What is Impulse?
Impulse It is not convenient to measure the varying force of impact. Suppose that $\vec{F}_{\mathrm{av}}$ is the average force acting during impact and $t$ is the small time for which the impact lasts. In such situations, it is found that the quantity $\vec{F}_{\mathrm{av}} \cdot \mathrm{t}$ is very easy to measure. The quantity $\vec{F}_{\text {av }} \cdot t$ is called impulse. If a variable force acts on a body or particle for a interval of time $t_{1} \rightarrow t_{2}$ Impules is $\vec{I}=\i...
Read More →What is Newton's Second Law of Motion?
Newton's Second Law of Motion According to this law, the rate of change of momentum is directly proportional to the applied force. The change in momentum takes place in the direction of applied force. Newton's II law gives the quantitative definition of force. i.e. $\quad \vec{F}=\frac{\Delta \vec{p}}{\Delta t}$ If $\Delta t$ is vanishingly small then $\vec{F}=\frac{\overrightarrow{d p}}{d t}$ Out of Newton's three laws of motion, the most fundamental one is the second law, because I and III law...
