  • What are some examples of elastic objects?

    The springs. The base of a trampoline. The bow to shoot arrows. Fishing rods. The mattresses. Rubber bracelets. The clothes. The chewing gum, when chewed. Which material is an example of elasticity? Rubber has elastic properties in varying degrees. Plastic, on the other hand, is not as elastic. It tends to deform when stretched, which…

  • What is the formula of elongation?

    Elongation = É› = (ΔL/L) x 100 Elongation at Break is measured in % (% of elongation vs. initial size when break occurs). The maximum elongation i.e., at break, emax is also called “strain to failure”. Ultimate elongation values of several hundred percent are common for elastomers and film/packaging polyolefins. What is E in elongation…

  • What is quantum meditation?

    Quantum Healing Meditation combines practical science with intangible spirituality. Popularised by Deepak Chopra, it aims to create physical change in the body through intention and visualization. Through creative and spontaneous visualization, the practice is said to strengthen the immune system and heal the body. What is quantum physics and spirituality? By “spirituality”, we mean a…

  • What cos means in physics?

    Definition of cosine The cosine of an angle is defined as the sine of the complementary angle. The complementary angle equals the given angle subtracted from a right angle, 90°. For instance, if the angle is 30°, then its complement is 60°. Generally, for any angle θ, cos θ = sin (90° – θ). What…

  • What is convergence in physics?

    Hint: The word converges or convergent in science generally means meeting or joining of objects or bodies at a point or plane. Therefore, it can be deduced that a convergent beam of light means a beam of light, whose individual rays keep on coming closer constantly and finally meet at a point. What is convergence…

  • What is cold light science?

    Definition of cold light 1 : light emitted by any body whose temperature is below that of incandescence — compare luminescence. 2 : visible light from whatever source unaccompanied by appreciable amounts of infrared and having therefore little heating effect. What are the 4 types of luminescence? There are many different types of luminescence including…

  • What is the component method?

    The component method is one way to add vectors. In this example we will be adding the two vectors shown below using the component method. The vectors we will be adding are displacement vectors, but the method is the same with any other type of vectors, such as velocity, acceleration, or force vectors. What is…

  • What is Rigid Body In c4d?

    Rigid Bodies are objects that fall, collide, bounce and more – in short, they interact with forces and with each other. Rigid Bodies interact with simulated natural forces and with each other. What is MoGraph in Cinema 4D? So, what is MoGraph? It’s a group of objects which allow for procedural modeling and animation within…

  • What is cantilever formula?

    Cantilever Beam Equations (Deflection) Sample Cantilever Beam equations can be calculated from the following formula, where: W = Load. L = Member Length. What is a cantilever and example? A cantilever is any rigid object that is fixed at one end and extends out over empty space. Street signs, airplane wings, shelves, fan blades, and…

  • What is the old name of physics?

    Physics was known as natural philosophy until the late 18th century. Which book is best for basics of physics? The Feynman Lectures on Physics. The Millenium Edition, Vol. Brief History of Time. From the Big Bang to Black Holes. University Physics with Modern Physics. Hugh D. Fundamentals of Physics. Basic Physics. The Elegant Universe. Physics…

  • How does balancing a stick work?

    Balance the stick on one finger. The balance point should be half way along. This is because the mass of the stick is the same on each side, so gravity pulls down on each side with equal force. As the stick is an even width, the balance point will be in the centre. What is…

  • What is the difference between theoretical physics and applied physics?

    Basically it’s the same in any field. There is a theoretical framework from which one can draw to develop solutions to real problems. Some would say applied physics is engineering, but then engineering has its own distinctions and even a sub topic ‘theoretical mechanics. Which is better applied physics or physics? There is no sharp…

  • What happens when you add forces?

    The net force is the vector sum of all the forces. That is, the net force is the resultant of all the forces; it is the result of adding all the forces together as vectors. For the situation of the three forces on the force board, the net force is the sum of force vectors…

  • What is the formula for time in acceleration?

    Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction. Created by Sal Khan. Is there…
