What is the relative amount of kinetic energy?
Kinetic energy is proportional to the square of an object's velocity, so the relative amount of kinetic energy depends on the velocities of the objects in question. If one object is moving faster than another, it will have more kinetic energy. The ratio of their kinetic energies will be the square of the ratio of their velocities.
What is the ratio of the kinetic energy if ball A has triple the mass and speed of ball B?
The ratio of kinetic energy is 9:1. Kinetic energy is directly proportional to mass and speed squared, so if ball A has triple the mass and speed of ball B, the kinetic energy of ball A will be 9 times that of ball B.
Light with an energy equal to three times the work function of a given metal causes the metal to eject photoelectrons. What is the ratio of the maximum photoelectron kinetic energy to the work functio?
The maximum photoelectron kinetic energy is given by the equation: Energy of incident light - Work function. If the energy of the incident light is three times the work function, then the maximum kinetic energy of the photoelectrons will be three times the work function. Therefore, the ratio of the maximum photoelectron kinetic energy to the work function is 3:1.
What is the efficiency of a car that uses 400000 J of energy from gaseline to make 48000 J of kinetic energy?
The efficiency of the car can be calculated as the ratio of the useful output energy (kinetic energy) to the input energy (energy from gasoline). In this case, the efficiency would be (48000 J / 400000 J) * 100% = 12%. This means that 12% of the energy from gasoline is being converted into kinetic energy.
Two bodies of equal masses are moving with uniform velocities v and 2v.Find the ratio of their of heir kinetic energies?
Kinetic energy is equal to the mass of the object times the velocity squared (Ek=.5mv2). To obtain the ratio between the two objects, divide the first by the second (Ek1/Ek2). This is equivalent to .5m1v12/.5m2v22. Since the masses are equal, they cancel out and you are left with v12/v22. Next, as stated in the problem, the seceond velocity is twice as much as the first so plug that coefficient into the aforementioned equation. (1v12)/(2v22). Since the values of velocity (v) are equal in this problem, they can cancel out just as the masses did. Now, 12=1 and 22=4; so the ratio is 1/4.
How do you find the ratio of kinetic energy?
The answer depends on what two (or more) things the ratio is meant to compare. The kinetic energy of several objects? The kinetic energy of an object compared to its total energy? The kinetic energy compared to its engine size?

Kinetic energy divided by potential energy equals?
The ratio of kinetic energy to potential energy is variable, as it depends on the specific situation. In general, kinetic energy represents the energy of motion, while potential energy represents stored energy due to an object's position or state. The ratio of kinetic to potential energy can provide valuable insights into the dynamics of a system.

Consider a motorcycle of mass 150 kg one wheel of which has a mass of 10 kg and a radius of 30 cm What is the ratio of the rotational kinetic energy of the wheels to the total translational kinetic?
The rotational kinetic energy of the wheel can be calculated as (1/2)Iω^2, where I is the moment of inertia of the wheel and ω is its angular velocity. The total translational kinetic energy of the motorcycle can be calculated as (1/2)mv^2, where m is the total mass of the motorcycle and v is its velocity. The ratio of the rotational kinetic energy of the wheels to the total translational kinetic energy is then (1/2)(Iω^2) / (1/2)(mv^2).
Is the ratio of an objects mass to its volume called potential energy?
No, the ratio of an object's mass to its volume is called density. Potential energy refers to the energy stored within an object due to its position or condition, such as gravitational potential energy.

What is the effiency of a motor that converts100j of electrical energy into 70j of useful kinetic energy?
The efficiency of the motor can be calculated as the ratio of useful output energy to input energy. In this case, the efficiency would be 70J (useful kinetic energy) divided by 100J (electrical energy) multiplied by 100% to get a percentage. So, the efficiency of the motor is 70%.
What energy the total energy of the motion of all particles in an chemical combined in a set ratio?
The total internal energy of a chemical system is the sum of the kinetic and potential energies of all its particles. The kinetic energy relates to the motion of the particles, while potential energy considers the interactions between particles. Their distribution is determined by the specific conditions of the system.
How the kinetic energy of an object changes when the speed of object doubles?
Kinetic energy at velocity "V" is (0.5) x mass x V x V Kinetic energy at velocity "2V" is (0.5) x mass x 2V x 2V Ratio of KE at velocity 2V and KE at velocity V is [(0.5) x mass x 2V x 2V] / [(0.5) x mass x V x V] = 4 So if the velocity double, KE quadruples
