motion detector is not measuring the position of some other object than the intended object—keep other things out of the region in front of the detector. Be sure the track is level and clean (to reduce friction). Experiment 1a—constant velocity in positive direction: Place the cart about ...

Set each sensor to the ±10 N setting and securely attach it to the top of a cart. Place the carts at rest on the track. Calibrate both sensors by selecting Experiment/Calibrate and then selecting either sensor. On the pop-up menu, check both sensors and select Calibrate Now. You will...
Newton's three laws of motion and how these fundamental principles describe how objects in the Universe behave when subjected to forces.
Force and motion are key topics in physics. Help students learn what they need to know, and have fun in the process, by playing some of these force...
The magnitude of these forces changed in whenever the direction of motion reversed. They were felt by participants during an experiment that required them to scan a virtual surface, represented by a planar haptic interface, via left-right motions of the index finger. We found that individuals ...
The EGFP-xTalin1 SiMS and the xTalin1-EGFP SiMS switch the motion from stationary to flowing. Insets show trajectories of the same xTalin1 SiMS. c Box-and-whisker plots of the distance (Δx) in the flow direction between the position at the stationary state and the first position where ...
Whole-body motion capture and hand interaction force data were collected. (b) Close-up of custom force handle. (c) Gait parameter calculations. The novice’s step frequency (f) and step length (L) were calculated using foot marker data. The novice’s gait velocity (v) was calculated ...
The experiment data for the threshold distance qualitatively agreed with the theoretical predictions, except when the separation distance was very small. Then, it was discovered that the free bubble became trapped near the attached bubble when the separation distance between the two bubbles was very ...
How is the motion of an object related to the size of the object and the amount of force that is applied to the object? What is gravity and how does it affect things on the earth? How do simple machines make work easier for people? The motion of an object can be describes by its ...
