You are told 3 things...1. That there are two objects with equal masses. 2. Both objects are in motion. 3. One object has a greater kinetic energy than the other. How is this possible? (1 point)

Question

One object has a greater volume than the other object.

One object has a greater volume than the other object.

One object has a greater speed than the other object.

One object has a greater speed than the other object.

One object has a greater density then the other object.

One object has a greater density then the other object.

One object is blue and one object is red

Answer 1

The situation can be explained by the relationship between kinetic energy and speed. Kinetic energy (KE) is given by the formula:

$$KE=\frac{1}{2}m{v}^2$$

where $m$ is mass and $v$ is velocity (speed). Since both objects have equal masses, if one object has a greater kinetic energy than the other, it must have a greater speed. Therefore, the correct choice is:

One object has a greater speed than the other object.
