Question

some points on normal force​

Answer 1

Answer:

• Normal force is the force that the ground (or any surface) pushes back up with. If there was no normal force, you'd be slowly seeping into the ground. The normal force on a object is always perpendicular (at a right angle) to the surface the object is on.

Answer 2

• Normal force is the force that the ground (or any surface) pushes back up with. If there was no normal force, you'd be slowly seeping into the ground.

• The normal force on a object is always perpendicular (at a right angle) to the surface the object is on.

• On a flat surface, the normal force of an object is {\displaystyle mg} {\displaystyle mg} (the object's weight, that is its mass multiplied by the force of gravity).
