An experiment was designed to determine the relationship between the angular
acceleration of the flywheel, the down
Average Velocity from a Position vs. Time Graph
Learning Goal: To learn to read a graph of position versus time and to calculate average velocity.
In this problem you will determine the average velocity of a moving object from the graph of its position as
Direction of Velocity and Acceleration Vector Quantities Conceptual Question
For each of the motions described below, determine the algebraic sign ( , , or ) of the velocity and
acceleration of the object at the time specified. For all of the motions, the
Red Light, Green Light
A car and a train move together along straight, parallel paths with the same constant cruising speed At the car driver notices a red light ahead and slows down with constant acceleration .
as the car comes to a full stop, the
Relative Velocity vs. Time Graph Ranking Task
Two cars travel on the parallel lanes of a two-lane road. The cars are at the same location at time
, and move in such a way as to produce the velocity (relative to the ground) vs. time graph shown in the figu
Tossing Balls off a Cliff
Learning Goal: To clarify the distinction between speed and velocity, and to review qualitatively onedimensional kinematics. A woman stands at the edge of a cliff, holding one ball in each hand. At time , she throws one ball stra
Consider the motion of a power ball that is dropped on the floor and bounces back. In the following questions, you will describe its motion at various points in its fall in terms of its velocity and acceleration. PartA You drop a power ball on the floor.
Here is a plot of velocity versus time for a particle that travels along a straight line with a varying velocity. Refer to this plot to answer the following questions. PartA What is the initial velocity of the particle, ?
Express your answer in meters per
What x vs. t Graphs Can Tell You
To describe the motion of a particle along a straight line, it is often convenient to draw a graph representing the position of the particle at different times. This type of graph is usually referred to as an x vs. t graph
PartA At what time(s) do the rockets have the same velocity? at time at time at times only only and and
at some instant in time between at no time shown in the figure
PartB At what time(s) do the rockets have the same x position? at time at time a
