· Forces occur when two forces interact (interaction forces).
· If you push against something it pushes equally hard back.
· So you push down on a table with 10N of force, it pushed back with 10N or it breaks, and dies, and sets on fire.
· Moving objects experience friction;
o Friction between two gripping forces which stops them from moving.
o Friction between two sliding surfaces.
o Resistance from liquid or gas. You push the molecules out the way causing friction, which is why you get friction, think aerodynamics.
