Question

What is the relationship between the speed of an object and its kinetic energy?

Answer 1

Answer:

For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.

Explanation:

Answer 2

The kinetic energy of an object is directly proportional to the square of the speed of the object.

Explanation:

The kinetic energy is the measure of energy exerted by the object during its state of motion. The kinetic energy depend on the mass of the object and the speed the object is moving. So, the kinetic energy is related to square of the speed of the object.

       $\text { Kinetic energy }=\frac{1}{2} \times \text { mass of the object } \times \text { (velocity of the object) }^{2}$

Thus, kinetic energy is directly proportional to the square of the speed of the object. So, as the speed of the object increases the kinetic energy increases double the times of its speed of the object.
