2017年12月4日 · The coordinates that describe a vector change when the coordinate system is changed. The left component of a vector is not a scalar. There is a 1-D mathematical vector space parallel to the left coordinate of a vector. If you rotate the coordinate system, it may be parallel to what has become the forward component.

2019年4月23日 · Motion is represented by velocity (vector) or speed (scalar) when the motion is restricted to one dimension. Other representations of motion include angular speed (scalar) and angular velocity (vector). An area, as such, is a scalar quantity, but you can define a vector corresponding to that area, and that vector is called an area vector.

2024年5月20日 · Force can be a scalar or a vector, F= mv2/r is a scalar force and F= hc/r2is also a scalar . Fields in Physics are generally both scalar and vector or Quaternions.

Force is a push or pull that changes or tends to change the state of rest or of uniform motion, the direction of motion, or the shape and size of a body. Force is a vector quantity because it has a magnitude as well as a direction.

Vector Quantities – Force, Electric field, Angular Momentum, Magnetic Moment, Linear Momentum, Average Velocity. Now we are familiar with what are vectors and scalars. Now if somebody asks if acceleration is a vector or a scalar, we can easily tell that it’s a vector because it has direction as well as magnitude.

2024年5月27日 · Both! Force is a quaternion quantity, the sum of a scalar force and a vector force. For example there are two gravitational forces, the scalar force Fs= - GmM d/dr 1/r = GmM/r^2 and the vector ...

And if you say the direction of both, well then, it isn't always the same! A force can do work on a body even displacing at an angle to the direction of force ($\theta$!). =>Note that when $\theta$ is $90^\circ$, the result will be zero ($\cos 90^\circ = 0$). When force and displacement are perpendicular, the force does no work on the body!

Torque (Force Moment) is a vector that describes the location of the Force line of action. Lemma: If you give me a force vector ${\vec F}$ and a moment vector about the origin ${\vec M}$ then I can define a line whose points obey the relationship $\vec{M} = {\vec r} \times {\vec F}$.

2024年5月23日 · Velocity and force are examples of vector quantities, while speed and temperature are examples of scalar quantities. The main difference between a scalar and a vector quantity is?

Difference Between Scalar and Vector. A scalar quantity is different from a vector quantity in terms of direction. Scalars don’t have direction, whereas a vector has. Due to this feature, the scalar quantity can be said to be represented in one dimension, whereas a vector quantity can be multi-dimensional.
