First, let us consider a sled of mass m being pulled by a constant, horizontal force of magnitude F along a rough, horizontal surface. The sled is speeding up.

how many major forces are acting on the sled? would it be 4 forces? gravity, normal, tension and kinetic?

Yes,there are 4 forces acting on the sled.That 'kinetic' hopefully stands for 'kinetic friction force'...What tension...?There's the force that pulls the sled,F,there's no tension.

Gravity - yes. Kinetic (friction force) - yes. No tension.. well none that's really on the sled. Normal force - yes. And finally, the horizontal force. You get a nice diagram of 4 forces all on every side of the sled.
