What is the independent variable?
The variable that the experimenter manipulates
|
What is the system?
A portion of the universe that has been chosen for studying the changes that take place within it in response to varying conditions within and outside of it.
|
What are position and clock reading?
The two fundamental variables that are measured in our experiments to describe motion.
|
What is find the slope of a tangent line to the curve at that clock reading?
How to find the instantaneous velocity at a clock reading when given a position vs. time graph.
|
What is the net force?
The vector sum of all the forces acting on an object.
|
|
What is the vertical axis?
The axis on a graph where the dependent variable is plotted
|
What is kinetic energy?
Energy that is stored in the motion of an object.
|
What is velocity?
The physical significance of a slope of a position vs. time graph.
|
What is acceleration?
The physical significance of the slope of a velocity vs. time graph.
|
What is 0?
The amount of force needed to keep an object weighing 4 N moving at a constant speed across a frictionless surface.
|
|
What is the slope of the graph?
The rate of change of y with respect to x
|
What is potential energy?
The general name for all accounts in which energy is stored in a system due to the configuration of the system.
|
What is displacement?
How far and object is from where it started, and in what direction.
|
What is displacement?
The physical significance of the area of a velocity vs. time graph.
|
What is 45 N?
The weight of a 4.5 kg object on the earth.
|
|
What is a direct proportion?
The type of relationship shown by a linear graph with a zero y-intercept
|
What is the Law of Conservation of Energy?
A law that states that the total amount of energy in a closed system is constant
|
What is x = -5 m/s*t + 40 m?
A mathematical representation of the relationship between position and time for an object that starts at a position of 40 m and moves in the negative direction at a constant speed of 5 m/s.
|
What are speed up, slow down, and change directions?
Three things an object might do that indicate it is accelerating.
|
What is the force of gravity on the sun by the earth?
The Newton's Third Law pair to the force of gravity on the earth by the sun.
|
|
What is 2?
The number of variables that change in a controlled experiment
|
What are working, heating, and radiating?
Three processes that transfer energy into or out a system
|
What is 4 mi/h?
The average speed of a jogger who runs the 1 mile at 6 mi/h, and then walks 1 mile at 3 miles/hour.
|
What is positive?
The direction of the acceleration when an object slows down while moving in the negative direction.
|
What is 500 N?
The size of the force on a baseball bat by a 0.5 kg ball moving 50 m/s when the bat strikes the ball with a force of 500 N and accelerates it toward the center field wall.
