What determines an objects kinetic energy? A. Weight and position b. Weight and speed. C. Mass and speed.D. Mass and position.
C. Mass and speed.
C. Mass and speed.
To determine an object's kinetic energy, you need to consider its mass and speed. The correct answer is C. Mass and speed.
Kinetic energy is the energy that an object possesses due to its motion. It depends on two factors:
1. Mass: The amount of matter an object contains. Objects with larger masses have more kinetic energy compared to objects with smaller masses, assuming they have the same speed.
2. Speed: The rate at which an object moves. The kinetic energy of an object increases with an increase in speed. Specifically, the kinetic energy is directly proportional to the square of the object's speed. This means that if you double the speed of an object, its kinetic energy will increase by a factor of four.
Therefore, the correct answer is C. Mass and speed determine an object's kinetic energy.
