forces listen which option(s) would correctly describe normal force? (select all that apply) a force that acts in the same direction as gravitational force a contact force a field force a supportive force that acts at right angles to a surface and helps support an object sitting on that surface

Answer

Explanation:

Step1: Recall normal - force definition

Normal force is a contact force that acts perpendicular (at right - angles) to the surface in contact and supports an object on that surface.

Step2: Analyze each option

  • Option 1: Normal force acts perpendicular to the surface while gravitational force acts downwards towards the center of the Earth. So, it does not act in the same direction as gravitational force.
  • Option 2: Normal force occurs when two objects are in contact, so it is a contact force.
  • Option 3: Field forces like gravitational and electromagnetic forces act at a distance. Normal force is not a field force as it requires contact.
  • Option 4: By definition, normal force is a supportive force that acts at right - angles to a surface and helps support an object sitting on that surface.

Answer:

B. a contact force, D. a supportive force that acts at right angles to a surface and helps support an object sitting on that surface
