Question

Which of the following objects has the greatest kinetic energy?

Answer 1

Answer:

A baseball flying through the air at 90 miles per hour.

Explanation:

Kinetic energy is a type of energy that an object has because of its motion. In this example, a baseball that is flying through the air would have kinetic energy because of this movement. In order to move this object, a force needs to be applied to it. In order for us to know the kinetic energy of an object, we have to look at both the mass and the speed. In this case, this ball would have the greatest kinetic energy because it has the greatest speed.

Answer 2

Answer:

a baseball flying through the air at 90 miles per hour

Explanation:

For the question, Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If the velocity is doubled the kinetic energy will increase by a factor of four.
