When a muscle works to generate enough force to rotate a bone, the measure of that force is termed torque. Since torque provides the bone with angular acceleration, it is studied as a vector quantity and the direction of this vector is dependent ...
Remember, a vector is defined in mathematics as a quantity that can only be fully described by both a magnitude and a direction.It’s worth noting that both velocity and acceleration are vectors. But velocity is the speed that something is going in a particular direction, while accele...
The velocity is a vector quantity, i.e: it has a direction as well as a magnitude. If the velocity has to change, there must be acceleration. There must be an acceleration to change the direction even if it does not change the magnitude of the velocity. In uniform circular motion, the...
Why is Tangential acceleration = alpha*Radius? Why does bending your legs when running enable you to swing your legs to and fro more rapidly? Why is the pressure on the front tires higher than the pressure on the rear tires in a car but t...
No, it doesn't.Velocity is a vectorial quantity, it has magnitude (speed) and direction. Even though the speed is constant in this particular example, the direction changes all the time. What is the difference between speed velocity and acceleration?
aThe driver is constantly updated with information about vehicle’s acceleration, braking, battery charge and location which is useful for the driver. 司机经常更新以关于车的加速度,刹车,电池为司机是有用的充电和地点的信息。 [translate] astrains 张力 [translate] ...
In essence, d/dt can apply to various quantities, while d(theta)/dt is focused solely on angular change. When should I use d/dt instead of d(theta)/dt? You should use d/dt when dealing with any variable that changes with respect to time, such as position, velocity,...
The purpose of this condition is twofold: (i) to convert the current quark mass into the constituent quark mass through a shift of mass, and (ii) to balance scalar attraction and vector repulsion of the mean field for confining the quark to nuclei [17]. The findings of these studies are...
Since energy and momentum together build a four-vector you get the relation between energy and momentum in an arbitrary inertial frame by . In covariant form this "on-shell condition" reads . From this it's also clear that , the invariant mass of the particle, i...
Find the vector's magnitude and direction. a) Find the magnitude of the current in the figure given below. b) Find the direction of the current. What is the difference between scalar and vector quantity? What is the difference between vector and a scalar quantity?...
