Vectors
A vector with no direction.
What is a scalar
A "bummer man" or an aerodynamic force opposing an aircrafts motion through air due to friction.
What is drag
The force that pulls all objects toward the center of Earth or another massive object.
What is gravity
The normal force experienced by an object resting on a ramp is equal to what other force experience by the object?
What is the gravitational force in the Y direction or Fgy

What is oxygen?
The length of a vector is representative of this quality.
What is magnitude
Although it moves easily, a sled in the snow, experiences this type of friction.
What is kinetic or sliding
The force between two surfaces sliding against one another.
What is friction

Basketball players are commonly seem wiping the bottom of their sneakers during competitions. This helps increase the amount of this type of friction that will keep them from slipping on the court.
There are two forces acting on an object. 10 N to the right at 0 degrees from the horizontal and 5 N up at 90 degrees from the horizontal. What is the magnitude and direction of the equilibrant.
What is 11 N at 206 degrees (or 64 degrees from vert; -26 degrees from horiz.)

What is canis minor
This ancient greek philosopher is credited with forming the mathematical relationship between the areas of the squares of both sides of a right triangle to the square of the area of the hypotenuse.
Who is Pythagoras
Not by miracles do an eraser work, but by friction that removes this from paper.
What is graphite
What is friction
If you know both the x and y components of gravity, you can use this trig function to find the angle of the inclined plane?
What is inverse tangent
Isolated females of this largest living lizard, a type of monitor, sometimes reproduce without having their eggs fertilized by a male.
What are Komodo dragons

This cool song written by rapper Rob Van Winkle rose to number one in 1989, describes frictionless children. The melody was influenced by Queen and David Bowie's hit song about pressure.
What is Ice Ice Baby
An object rests on a ramp. If the ramp is increased the normal force will increase, decrease, or stay the same?
What is decrease
The magnitude of acceleration will be greater for an object moving freely up or down an inclined plane?
What is up the inclined plane
Hey farmer! It's the physics term for a region in which every point is affected by a force.
