In physics and mechanics, compression refers to the application of a compressive force to an object, leading to its deformation by squeezing or pressing inward and resulting in a decrease in size or volume. This force is encountered across diverse fields, including structural engineering, material testing, and … Read more

Newton’s third law of motion states that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object. In other words, every action force has a corresponding reaction force of the same magnitude but in … Read more

The information on this page is ✔ fact-checked. Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In simpler terms, when a force is applied to an object, it will accelerate in the direction of the … Read more

Newton’s first law, also known as the law of inertia, states that an object will maintain its state of rest or uniform motion in a straight line unless acted upon by an external force. In simpler terms, if there are no unbalanced forces acting on an object, … Read more

The information on this page is ✔ fact-checked. A frame of reference, also known as a reference frame, is a theoretical framework that establishes a coordinate system and a set of reference points. It provides a basis for measuring and describing the position, velocity, and other properties of objects within that frame. The coordinate system … Read more

It acts in the opposite direction to the motion of the object or the force that is attempting to cause the motion. Friction is caused by … Read more

It is a vector quantity, meaning it has both magnitude and direction. In simpler terms, velocity measures both how quickly an object’s position is changing and the direction in which it is changing. … Read more

It is an intrinsic characteristic of an object and remains constant regardless of its location. The kilogram (kg) serves as the standard unit of mass, commonly used to express the mass of different objects. For example, the mass … Read more

The information on this page is ✔ fact-checked. Momentum quantifies the motion of an object. It is determined by multiplying the object’s mass by its velocity. In simpler terms, momentum represents the amount of motion an object possesses. When an object is in motion, it has momentum. The greater the mass and velocity of the … Read more
