The correct answer is "Mass and speed." An object's kinetic energy is determined by both its mass and its speed. The equation for kinetic energy is KE = 1/2 * m * v^2, where KE represents kinetic energy, m represents the mass of the object, and v represents the velocity or speed of the object.
The correct answer is "Mass and speed."
Kinetic energy is determined by two main factors: the mass of the object and its speed.
The formula to calculate kinetic energy is:
KE = 0.5 * mass * speed^2
In this formula, "KE" represents the kinetic energy, "mass" represents the mass of the object, and "speed" represents the speed of the object.
The mass of an object refers to the amount of matter it contains. It is usually measured in kilograms (kg). The greater the mass of an object, the more kinetic energy it has.
The speed of an object is the rate at which it moves, usually measured in meters per second (m/s). The greater the speed of an object, the more kinetic energy it possesses.
Therefore, to determine an object's kinetic energy, you need to know its mass (in kg) and its speed (in m/s). By plugging these values into the formula mentioned above, you can calculate the kinetic energy of the object.
