RELATIONSHIP BETWEEN WORK AND KINETIC ENERGY
Introduction: In this experiment you will watch three videos to verify the work-kinetic energy theorem. The work-kinetic energy theorem states:
W = ΔK = 1/2 mvf2 − 1/2 mvo2
Equipment: Computer simulations.
Experiment Part 1 – Constant Force Parallel to the Block’s Velocity
The video is of a 1kg block that is being pushed across a frictionless surface by a constant force that is parallel to the block’s velocity. A force (in Newtons) vs. position (in meters) graph appears below the simulation. A kinetic energy (in Joules) vs. position (in meters) graph is also plotted for the motion. Be aware that the simulation plays very rapidly. Click the pause button so that you have time to read the graphs while answering the following questions.
Q1.1 What is the magnitude of the force acting on the block?
10 N
Q1.2 Describe, in words, how you would use the force vs. position graph in the simulation to obtain a value for the work done on the block after the block has moved a given distance. Be specific! Simply saying “read the graph” is not sufficient! Indicate what aspect of the graph you must read.
Work done by force acting on the block can be determined by calculating the area covered by force vs. position graph at the considered position.
The x axis of the force vs. position graph gives...
