Math Stuff
If you have two lengths of a right triangle, you can use this to find the other.
Pythagorean Theorem
Field force that pulls objects towards the ground.
Gravity
General term for friction involving movement.
Kinetic Friction
If an object moves with a force of 20 N in the y direction and 15 N in the x direction, what is its resulting magnitude of the force?
25 N
Something that has magnitude and direction.
Vector
Three trig functions that can be used to find angle measures and lengths.
Sin, Cos, Tan
Force that pushes up against gravity when there is contact.
Normal Force
Resistance created by two objects rubbing against each other.
Sliding friction
If an object moves with a force of 20 N in the y direction and 15 N in the x direction, what is its resulting direction? (As an angle measure)
53.13 degrees
Type of friction that has the least magnitude
Rolling friction
The process to find the coefficient of friction when given an angle that an object is sitting at.
Use Tangent
A term that means the sum of all forces acting on something.
Resultant
Type of friction that involves circular motion that greatly reduces the magnitude of the friction.
Rolling Friction
If an object on earth weighs 10 kg, what is its normal force?
98 N
Type of fluid friction that usually gets ignored in physics problems.
Air resistance
Formula relating normal force, coefficient of friction, and force of friction.
Ff=(mew)(Fn)
According to Obi-Wan, this energy field binds the galaxy together.
The force
Type of friction that acts on objects moving through air or water.
Fluid Friction

111.33 N
Type of friction that generally has the force with the most magnitude.
Static friction
How do you find an object's normal force?
Mass * Gravity
Force that is equal and opposite of the resultant.
Equilibrant
Type of friction that happens when one object is in contact with another object, but no motion is involved.
Static Friction
If an object is on a table that is tilted at a 30 degree angle, what is its coefficient of friction?
.577
