You measure the velocity of falling object at several times given in the table below. The acceleration is the slope of the fit line. Use the Data Analysis ToolPak in Excel(or any other linear regression tool)to determine the acceleration and ...
Acceleration due to gravity causes a falling object to pick up speed as it travels. Because a falling object's speed is constantly changing, you may not be able to measure it accurately. However, you can calculate the speed based on the height of the drop; the principle of conservation of...
在EdexcelA-LevelPhysicsTopic2A中,我们学习到了Terminalvelocity〔自由沉降速度〕,也称为终端速度。 【指任一颗粒的沉降不因流体中存在其他颗粒而遭到干扰时,在等速阶段里颗粒相对于流体的运动速度,即加速阶段终了时颗粒相对于流体的速度。】 或者根据课本中给出的定义,即Thevelocityofafallingobjectwhenitsweightis...
a pressure sensor for measuring a change of atmospheric pressure according to falling of the falling object; a memory part for storing time information and pressure information; and an output port arranged to be connectable to the device for measuring falling velocity of the falling object for prov...
A falling object reaches its terminal velocity when the gravitational and frictional forces are compensated. Therefore, the net force acting on the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can ...
The equations of motion in free-fall that we are going to use in this particular problem for the required velocity of the object are shown below: h=ut+12gt2v=u+gt, where, u is the initial velocity of the object, t is the total time of motion. g is the...
oTerminal velocity is the constant speed that a freely falling object eventually reaches. (终端速度是自由下落的物体最终达到的恒定速度。) oUnderstanding terminal velocity is crucial for designing safe parachutes. (了解终端速度对于设计安全的降落伞至关重要。) oThe concept of terminal velocity is often ...
