Final answer:
An object's kinetic energy is primarily determined by its mass and velocity, following the formula KE = (1/2)mv^2. Factors such as heat and height do not directly affect kinetic energy but might relate to potential energy instead.Both options B and C are correct .
Step-by-step explanation:
Factors Affecting Kinetic Energy
The kinetic energy of an object is affected by various factors, notably its mass and velocity. The formula for kinetic energy is KE = (1/2)mv^2, which shows that kinetic energy is directly proportional to the mass of the object and the square of its velocity. Therefore, factors such as heat, height, or static factors like position in a gravitational field do not directly affect kinetic energy. In this case, an increase in mass or velocity will result in an increase in kinetic energy.
Additionally, a common misconception is that height affects kinetic energy directly, but height actually relates to potential energy as it represents an object's potential to gain kinetic energy when falling under the influence of gravity. Hence, the correct factors from the options given that affect an object's kinetic energy are mass and velocity.
