Question 35

A person lifts a box from the floor onto a table.

This scenario exemplifies the application of force, as the individual must exert an upward force to overcome the gravitational pull on the box and successfully lift it onto the table.

A) A fully charged battery enables a flashlight to operate.

While a fully charged battery provides energy to power a flashlight, this option does not directly depict the application of force in a physical sense. The operation of the flashlight is more about energy transfer rather than the exertion of force on an object.

B) A cup of water freezes after being placed in a freezer.

This option describes a physical change in the state of water due to temperature drop, but it does not involve the application of force. Freezing involves thermal energy removal rather than a force being exerted on the water itself.

C) A person lifts a box from the floor onto a table.

This choice correctly illustrates the application of force, as the act of lifting requires the exertion of force against gravity. It demonstrates the concept of force in action, as the person must apply sufficient force to elevate the box.

D) A box slides at a constant speed on a frictionless surface.

Although the box is in motion, this scenario implies that no net force is acting on the box, as it is moving at a constant speed. Therefore, it does not represent the application of force in the same manner as lifting an object does.

Conclusion

The correct answer, "A person lifts a box from the floor onto a table," clearly depicts the application of force through the action of lifting against gravity. In contrast, the other options either involve energy transfer, physical changes without force, or motion without net force, making them unsuitable examples of force application.
