This phrase can be used when describing a physical phenomenon - meaning that an object's motion is caused by a certain force, such as friction or gravity. For example: "The motion of the stylus was caused by the heat generated by the laser."
The rotation of the plane of motion is caused by the Coriolis force.
This motion is caused by the motor protein dynein, which uses the energy of ATP hydrolysis to move along the microtubules, in a manner resembling the movement of myosin along actin filaments.
This opposite motion is caused by the intermediate S-wave term.
The irregularity of the motion is caused by bursting bubbles at the surface of the bed.
Efficient motion occurs when motion is caused by a thing that possesses the complete form of the particular motion caused; formal motion occurs when the moving thing has the incomplete form of the thing moved.
An interesting feature of the monorail bridge response is that sway motion is caused by torsional behavior resulting from eccentricity between the shear center of the bridge section and the train load.
Lugeon's work was closely connected with that of Hans Schardt, a Swiss geologist who had recognized that the Prealps were composed of folds that had advanced for tens of kilometres over the preexisting rock and who had proposed that this motion was caused by the gravitational creep or plastic flow of rock layers down gentle slopes.
The ground velocity at TKT showed pulse-like motion with a large PGV of 161 cm/s during the 1995 Kobe earthquake in Japan; the pulse-like motion was caused by the directivity effect (Kamae and Irikura 1998).
In 1905, Albert Einstein theorized that this Brownian motion was caused by the water molecules continuously knocking the grains about, and developed a hypothetical mathematical model to describe it.
Some have complained that the fake zooms, parallax effects and sliding motion are causing motion sickness, while others claim those same effects are sucking battery life.
Ptolemy believed that the heavenly bodies' circular motions were caused by their being attached to unseen revolving solid spheres.
