Honestly, yes. You're better off getting a family friend to explain things, because kids think their parents are complete idiots.
I believe that would be friction.
Friction That's what I believe what you are asking fir
Friction i do believe
difference between inherent and total moisture?
The force of friction is proportional to the force which surfaces press against each other. Since two people will cause the sled to push harder on the snow then one person, the friction will be greater for two people on the sled.
The friction between moving particles is called friction.
No it does not. It will actually reduce the friction between them.
Air friction.
Friction between two objects produces heat.
Friction between the brake pad/lining and the rotor/drum and friction between the tyre and the road.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
static friction is the friction between two bodies they are in contact. And another sliding over the other. Kinetic friction is the friction between two bodies they are rolling .And that force is opposite to the rolling angle
