Mechanics drops can refer to a few different things depending on context, but generally it refers to a type of liquid used in mechanical applications to reduce friction, prevent wear, and provide lubrication. Mechanics drops can include things like motor oil, hydraulic fluid, and gear lubricants, which are used in engines, transmissions, and other mechanical…
Buoyancy is a physical principle that describes the upward force exerted by a fluid (such as water or air) on an object that is partially or fully immersed in it. This force is equal to the weight of the displaced fluid and is known as the buoyant force. According to Archimedes’ principle, an object will…
Pressure in a fluid is the force per unit area that the fluid exerts on the surface it comes in contact with. This pressure is a result of the motion and collisions of the individual particles of the fluid, such as molecules or atoms, and is described by the fluid’s properties, such as its density…
Acceleration due to gravity is the acceleration experienced by an object in the gravitational field of a massive body, such as a planet, moon, or star. The acceleration due to gravity is denoted by the symbol “g” and is usually measured in meters per second squared (m/s²). The value of acceleration due to gravity depends…
Young’s modulus, also known as the modulus of elasticity, is a measure of the stiffness of a material. It is defined as the ratio of stress to strain within the elastic limit of the material. In other words, it measures the amount of stress required to produce a certain amount of strain in a material.…
Linear refers to something that is straight or follows a straight line. In mathematics, a linear function is a function that has a constant rate of change, meaning that as the input variable increases by a fixed amount, the output variable also increases by a fixed amount. The graph of a linear function is a…
When a point mass collides with a rigid body, the collision can be classified as either elastic or inelastic. In an elastic collision, the total kinetic energy of the system is conserved. That is, the kinetic energy of the point mass and the rigid body before the collision is equal to the kinetic energy of…
Conservation of angular momentum is a fundamental principle in physics that states that the total angular momentum of a system is conserved in the absence of external torques. Angular momentum is a property of rotating objects and is defined as the product of the moment of inertia and the angular velocity. In simpler terms, the…
The perpendicular axes theorems are a set of rules used in the study of moments of inertia, which are physical properties of objects that describe how difficult they are to rotate around various axes. The perpendicular axes theorems state the following: These theorems are very useful in determining moments of inertia for objects with complicated…
Moment of Inertia is a measure of an object’s resistance to changes in its rotational motion. It is defined as the sum of the products of the mass of each particle in the object, and the square of its distance from the axis of rotation. The moment of inertia of an object depends on its…
