A simple pendulum consists of a relatively massive object hung by a string from a fixed support. It typically hangs vertically in its equilibrium position. The massive object is affectionately referred to as the pendulum bob. When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position. The motion is regular and repeating, an example of periodic motion.

Newton`s first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. This is also known as the law of inertia. Inertia is the tendency of an object to remain at rest or remain in motion.

Isaac Newton`s First Law of Motion describes the behavior of a massive body at rest or in uniform linear motion, i.e., not accelerating or rotating. The First Law states, A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force.

inertia is the nature of the body to resist the change in its state and mass is the amount of matter in the body. Inertia of the body depends on the mass of the body.

Random acceleration
B
Infinite acceleration
C
Variable acceleration
D
Uniform acceleration
This gravitational force is due to the uniform acceleration due to gravity which is considered constant near the surface of the earth and is equal to g = 10m / s2. Thus a freely falling body falls with the uniform acceleration and so it has non zero velocity or the velocity keeps on increasing.

Speed
The distance travelled by an object in a specific direction is called displacement. Displacement is a vector quantity. This means that it can be defined only when proper magnitude and direction are mentioned.

Linear momentum is defined as the product of a system`s mass multiplied by its velocity. In symbols, linear momentum is expressed as p = mv. Momentum is directly proportional to the object`s mass and also its velocity. Thus the greater an object`s mass or the greater its velocity, the greater its momentum.
