Coordinates & Graphing
This is the ratio of the rise over the run
What is slope?
This is how far an object has traveled
What is distance?
This is the quadrant where both +x and +y values will be found
What is quadrant I?
This is the unit of force we use in the USA to denote the pull of gravity on our bodies.
What are pounds?
This is the force that pulls objects toward the surface of the earth.
What is gravity?
This is the variable that the investigator changes intentionally.
What is the independent variable?
This is known as the distance an object travels per unit of time
What is speed?
This is the equation to solve for the acceleration of an object.
What is a= v/t
This is the force required to accelerate 1kg at 1m/s
What is the Newton?
This is the force that pushes back up against your dog when she's lying on the floor.
What is the normal force?
The variable is found on the y-axis.
What is the dependent variable?
This is speed with direction
What is velocity?
This is the acceleration of a ping-pong ball that starts from rest and moves at 6 m/s after 3 seconds.
What is 2 m/s2?
This is the pounds equivalent to a Newton.
What is 4.448N?
This force opposes motion when two objects are not moving past one another
What is static friction?
This is the type of line on a speed vs. time graph that shows when an object is at a constant speed.
The speed at any given point in time.
What is instantaneous speed?
If someone weighing 500 N sits in a chair, this is the amount of normal force pushing up on each leg of the chair
What is 125N?
This is the force of gravity on earth
What is 9.8N/kg
This is a device that increases the force of friction
What are car breaks, cleats, shoe soles, etc... ?
On a sloping, curved line, up and to the right, this is what can be about the car's motion.
What is "the car is accelerating"?
This is the rate at which velocity changes.
What is acceleration?
This is the mass of a penguin that weighs 300N on earth
What is 30.6 kg?
This is the equation we use when solving weight problems.
w=mg
This is the result of when the net force is zero (balanced forces)
What is equilibrium?
