Mass and speed determine an object's kinetic energy.
The correct answer is: Mass and speed. An object's kinetic energy is determined by both its mass and its speed. The formula for calculating kinetic energy is KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the speed of the object.
The correct option that determines an object's kinetic energy is mass and speed.
To understand why, we need to define what kinetic energy is. Kinetic energy is the energy an object possesses due to its motion. It depends on two factors: mass and speed.
1. Mass: The mass of an object is a measure of how much matter it contains. The more massive an object is, the more kinetic energy it will have. This is because an object with more mass requires more energy to set it in motion compared to an object with less mass.
2. Speed: The speed of an object refers to how fast it is moving. The faster an object is moving, the more kinetic energy it will have. This is because the energy associated with motion increases as the object's speed increases.
So, if you want to determine the kinetic energy of an object, you need to know its mass and its speed. By multiplying the mass by the square of the speed (using the equation KE = 1/2 mv^2), you can calculate the object's kinetic energy.
