Calculating Kinetic Energy in English Units - Physics Forums What is kinetic energy and how is it calculated in English units? Kinetic energy is the energy an object possesses due to its motion It is calculated using the formula KE = (1 2)mv^2, where m is the mass of the object in pounds and v is the velocity in feet per second 2
How Do You Calculate the Uncertainty in Kinetic Energy? - Physics Forums Energy Kinetic Kinetic energy Uncertainty In summary: You can't add apples and oranges In summary, the conversation discussed the calculation of kinetic energy for an object of mass m = 2 3 ± 0 1 kg and speed v = 1 25 ± 0 03 m s, using the equation K = (1 2)mv2 The uncertainty in K was also considered, with the formula Δz = |z| (Δx x
Solved a)find an expression for the kinetic energy of the - Chegg a) find an expression for the kinetic energy of the car at the top of the loop express the kinetic energy in terms of m,g,h,R b) find the min initial height h at which the car can be released that still allows the car to stay in contact with the track at the top of the loop express the min height in terms of R
Ranking Kinetic Energy: Why Does Mass Matter More Than Amplitude? 2 How is kinetic energy calculated? Kinetic energy is calculated using the equation KE = 1 2 * m * v^2, where m is the mass of the object and v is its velocity 3 What is the relationship between kinetic energy and speed? Kinetic energy is directly proportional to an object's speed This means that as an object's speed increases, its kinetic
Kinetic Energy in Spherical Coordinates - Physics Forums How is kinetic energy in spherical coordinates calculated? Kinetic energy in spherical coordinates is calculated using the formula E=1 2mv^2, where E is the kinetic energy, m is the mass of the object, and v is the velocity of the object in spherical coordinates 3
Verify that this kinetic energy operator is Hermitian - Physics Forums Yes, a kinetic energy operator can be non-Hermitian In general, a Hermitian operator is preferred in physics because it ensures the conservation of energy and the reality of energy eigenvalues However, there are certain cases where a non-Hermitian kinetic energy operator may be used, such as in non-Hermitian quantum mechanics
Why is kinetic energy not a vector - Physics Forums Fullperson said: Why is kinetic energy not a vector, though it uses velocity in its definition of : K = 1 2mv^2 Your confused with the difference between velocity and speed Kinetic energy does not use velocity in the equation you stated That equation uses speed, the magnitude of a velocity vector Since the magnitude of a vector is a scalar
Amount of energy, roughly, needed to kill with blunt force trauma A 1 ms smack requires more acceleration to kill you than a 100 ms smack Penetrating injuries to the head have a good chance of killing you The army long used 58 ft-lbs as the energy of a projectile (bullet or fragment) needed to cause a casualty, but that just assumed a hit and not necessarily a hit to the head
