HOOKE'S LAW Introduction In physics, Hooke's Law is one of the fundamental principles governing how objects deform under external forces . Named after the 17th-century British physicist Robert Hooke, this law provides a crucial understanding of the behavior of elastic materials, such as springs and rubber bands. Whether stretching a rubber band or compressing a spring, Hooke's Law helps explain what happens when forces act on these materials. What is Hooke's Law: Hooke's Law states that the force F needed to extend or compress a spring by some distance x is proportional to that distance. Mathematically, it is expressed as: F= -kx Here k represents the spring constant, which is the measure of the stiffness of the spring, and x is the displacement from the displacement position. The negative sign indicates that the force exerted by the spring is in the opposite direction of the displacement. Understanding the Spring Constant: The spring constant k is a critical co
Types of Motion
As in previous article I have discussed about the basics of Kinematics, and also discussed about the concept of Rest and Motion. In this article I am going to give you the concept of types of Motion.
So there are three types of Motion namely;
1. Translatory Motion
2. Rotatory Motion
3. Oscillatory Motion
1. TRANSLATORY MOTION
When all the points of the body moves uniformly along the same straight line, such motion is known as Translatory Motion.
For Example:
A train moving straight on a track is an example of Translatory Motion.
Translatory motion is further classified into;
(i) Linear Motion
(ii) Circular Motion
(iii) Random Motion
(i) LINEAR MOTION:
When any object moves along a straight path, then its motion is said to be Linear Motion.
For Example:
A bus moving on a straight path is an example of Linear Motion.
Motion of a body along circular path is called Circular Motion.
For Example:
An artificial satellite moving around the earth is an example of Circular motion.
(iii) RANDOM MOTION:
Irregular motion of the body is known as Random Motion.
For example:
You might have observed the motion of birds, do they fly in any specific direction?
Their motion is irregular which is perfect example of Irregular motion.
On the other hand, the motion of flies is also an example of Irregular motion.
ROTATORY MOTION
The motion of a body around fix axes which passes through body itself is called Rotatory Motion.
For Example:
The rotation of fan around a fix axis is an example of Rotatory Motion.
VIBRATORY MOTION
Back and fourth motion of any object is said to be the vibratory motion.
For example:
You might have observed the motion of a Swing. When you hold and release it from a specific point then it moves back and fro so it is the example of Vibratory Motion.
On the Other hand we have the motion of a Pendulum, it also moves to and fro so it can be said that its motion is also Vibratory Motion.
