None of the above - c. 5 m/s The slope of a velocity vs. time graph tells you a. position b. maximum velocity c. average velocity d. acceleration e. maximum position - d. acceleration Which of the following is a private research la...

NLN PAX Physics Exam (Answerd) Verified Solution Displacement Distance that an object is from some starting point, and it is measured in units of length. Motion when an object is in motion, it's displacement is constantly changing. -Velocity (speed) -Acceleration Speed Is the distance traveled by an object per unit of time. - Speed equals distance traveled over time. Velocity Speed in a given direction; it therefore tells us two things about a moving object, it's speed and direction...

What is natural movement in a gravitational field? - correct answerAll objects move in the direction of the g field on their own. Unnatural movement is against the field (when a force is exerted against the field). What is Displacement? - correct answerDisplacement is the change in location of an object. What is Velocity? - correct answerVelocity is the rate of change of displacement (x) v=x/t What is Acceleration? - correct answerAcceleration is the rate of change of velocity (v) a=v/t...
