5 days ago · Air Resistance Force: Air resistance force, also known as drag, opposes the motion of an object through air. It is a type of frictional force that depends on the object’s speed, surface area, and the density of the air. Spring Force: Spring force is the force exerted by a compressed or stretched spring upon any object attached to it. Hooke ...
3 days ago · A magnetic field (sometimes called B-field [1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2] : ch1 [3] and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
4 days ago · In physics, specifically in electromagnetism, the Lorentz force (or electromagnetic force) is the combination of electric and magnetic force on a point charge due to electromagnetic fields. A particle of charge q moving with a velocity v in an electric field E and a magnetic field B experiences a force (in SI units [1] [2]) of It says that the ...
Answer. In this example, we need to find the moment of a planar force about a point. Recall that the vector moment of force ⃑ 𝐹 acting at point 𝐴 about point 𝐵 is given by 𝑀 = 𝐵 𝐴 × ⃑ 𝐹. Let us begin by finding the vector 𝐵 𝐴 : 𝐵 𝐴 = ( 7, 3, 0) − ( 7, − 2, 0) = ( 0, 5, 0).
4 days ago · Hence spring constant/ force constant is defined as force per unit of extension or compression of the spring. Note: The sign in the equation is negative because force is opposite to the direction of applied force.it is the restoring force. The SI unit of force constant is N/m. Spring constant is inversely proportional to distance travelled by ...
1 day ago · This unit is defined as a twelfth of the mass of a free neutral atom of carbon-12, which is approximately 1.66 × 10 −27 kg. Hydrogen-1 (the lightest isotope of hydrogen which is also the nuclide with the lowest mass) has an atomic weight of 1.007825 Da. The value of this number is called the atomic mass.
