The attribute of inertia in a body is its ability to remain at rest or in motion until it is acted on by an external force. The inertial frame of reference takes this into account. Unless displaced by an external force, everyone examined in an inertial frame of reference tends to maintain their rest or […]

Generally speaking, a force is defined as the application of a push or pull to an object with mass in such a way that it will affect its motion even when the object is not being pushed or pulled in return. It has the ability to cause an object to move from its state of

The quantity of motion contained within a moving item is known as momentum. The external action of pulling or pushing something is known as force. A force causes a shift in momentum. When the velocity varies, the momentum changes, but when the acceleration changes, the force changes. Even if the velocity changes, the force remains

Inertia Sir Isaac Newton’s contributions to physics are unparalleled. In classical physics, his laws of motion altered everything. The first of his three laws of motion deals with inertia. So let’s begin by defining inertia.  The Latin word ‘iners,’ which means lethargic or idle, is the root of the English word ‘inertia.’ Kepler was the

Elastic and Inelastic Collisions Introduction We come across the term “collision” when we study science. This is because it has a significant role in physics. When one moving object collides powerfully with another entity, this phenomenon occurs. Is there a chance that the collision will lead to  different questions? Like, is it elastic or inelastic?

A rigid body is one on which the distance between two locations remains constant whatever force is put to it  or we can say a rigid body, on the other hand, is one that does not deform under the action of forces. However, in real life, there would be some force that causes the body

When studying kinetics, it is important to know about scalar and vector quantities. A quantity that possesses a specific magnitude but to a specific direction is called a scalar quantity, whereas a quantity that possesses a particular magnitude and direction as well is called a vector. One such important vector quantity is velocity which we

As per Newton’s laws of motion, force is an external force that can change the body’s state in rest and activity. However, this particular explanation doesn’t define the entire phenomenon. Therefore, force is an external agent that can cause energy buildup or displacement in a body. There are two major types of forces: contact and

Rest and motion are the two main attributes considered when defining a body’s physical state. As the name suggests, rest means a state of the body when it is static, or no displacement occurs. On the other hand, motion is considered the state where a body moves from one place to another. Several physical attributes

Linear momentum is a concept in physics that determines the product of the mass and velocity of a particle. It evaluates the force and analyses the impact of each particle. Students must understand the concept of mass and speed before understanding linear momentum. This way, they will understand the properties of the linear momentum of
