Acceleration
When you increase force, acceleration increases as well
Acceleration is directly proportional to force applied, but when you increase the mass by a cretain ammount, acceleration is divided by that ammount.
The equation for acceleration is: 
Friction
Even though things might seem smoth, there is friction at a molecular level that makes it harder to get something going. Each surface has individual "grooves" that interlock with the second surface. You have to use a bigge ammout of force to seperate the groves than to keep them seperate and sliding ontop of one another
The rougher the surfaces, the higher the friction will be. There are some examples of friction coefficients. You use this in the equation: F frict = (friction coeficient) * F norm

Newton's 2nd Law
F = m*a
The more mass something has, the more force it takes to get it moving, and the slower it changes velocity
Force is diectly proportionate to mass. :
-
No matter what the object is, wether it is big or small, it will fall to earth at tthe same speed as somethiing bigger or smaller than it.(ignoring air resistance)
The less mass something has, the easier it is to get it moving, but the quicker it loses velocity
When you drop a foam ball and a bowling ball from the same height, they will hit the ground at the same time, but when you drop a fether and a marble from the same heiht, the marble will hit the ground faster than the feather. This is because of air resistance. They both have the same relationship of force and mass, but the feather's proportionality of mass to air resistance is more than the marbles. This means that the feather experiances less net force (because gravity and air resistance arrows combined equals less than the
Newton's 3rd Law
For every action, there is an equal and opposite reaction.
-
When you push against something, it pushes back on you the same ammount. This happens when you walk on the earth, or when yo fire a gun. Every time you take a step, the earth moves a tiny bit, but because it's mass is so much greater than yours, it is insignifigant.
Free Body Diagrams
When you draw a free body diagram, F norm is pointing perpendicularly away from the surface. When this is on flat ground, it just points up, but when this is on an inclined plane, this points directly away from the surface. F grav is always pointing directly down, no matter the slope of the
-
To find F net, you have to cancle out the two arrow that are going parallel to the ground/surface that it's on.
to find the values of Fgrav when the object is on an inclined plane, F ll = mgsin(theta), and F⊥ = mgcos(theta). Theta is the angle of the plane
