Question

Which situation describes a non-contact force acting on an object?
-a person cutting an apple with an apple slicer
-a person picking up a textbook
-a person closing a door
-a person pouring water out of a pitcher

Answer 1

A non-contact force is a force that acts on an object without physical contact. Among the given situations, none of them explicitly demonstrate a non-contact force, as they all involve physical interaction. However, one might interpret "pouring water out of a pitcher" to invoke a non-contact force in the context of gravity acting on the water as it falls, but it isn't a classic example. The other options involve direct contact with the objects.

If we strictly consider the consideration of non-contact forces like gravity, magnetic force, or electrostatic force, none of the situations best illustrate those conditions effectively. If you're looking for a situation that could conceptually involve gravity as a factor while still considering physical interaction, pouring water could fit that brief. However, the most precise selection for a classical non-contact force example isn't included in these scenarios.
