When speaking of the effects of force on mass in the phenomenon of inertia, it can be easy to accidentally refer to force as "inertial force." This can probably be traced back to the terms "force" and "inertial mass." Force is an amount of energy that causes an object to change speed...
is defined as: both water bottles accelerate—but clearly there is a difference. the full bottle of water (with a greater mass) requires a larger force to accelerate. here you can see the connection between force, mass, and acceleration (often called newton's second law). this is that ...
“That’s when you have ignition, when the fusion reaction is starting to bootstrap itself enough that it’s producing more energy than the plasma uses.” Unlike magnetic confinement reactors like tokamaks and stellarators, inertial confinement ditches magnets and instead relies o...
The kinematics of the vehicle are modeled linearly and defined using general kinematic parameters(caster angle, kingpin angle, roll center height, etc.). This allows an easy workflow and streamlines the process of performing batch runs, where one or more system parameters are varied across multiple...
aThe general motion and load of the bearings can be completely described in five degrees of freedom. Thus, the displacements of the bearing center are defined in the inertial coordinate system and include not only the radial displacements x,y and a xial displacement z but also the rotations abo...

There's always a little confusion between mass and weight. Mass, which is the quantity you need to determine density, is a body's inherent inertial resistance to a change in motion, but weight is the force exerted by gravity on the body. Mass can be measured in kilograms, but weight is...
We define a cost function that considers the stresses in the servo, the angular momentum in the servo joint, which is related to the gear tooth stress, and the mass of the leg, displayed in Supplementary Fig. 3. The particle swarm optimization (PSO) is used to find the best set of ...
But it was René Descartes, the great French philosopher, who would add new depth and dimension to inertial motion. In his "Principles of Philosophy," Descartes proposed three laws of nature. The first law states that each thing, as far as is in its power, always remains in the same stat...
You define a rigid body by specifying its geometry, mass properties and interface with other parts. Each rigid body is identified and defined in isolation. In the above example, the mechanism is composed of four rigid bodies: A, B, C and D. The rigid body A is shown in isolation below...
