Acceleration is vector or scalar, Such as title

Acceleration is vector or scalar, Such as title

Acceleration is a vector.
The sign that separates a vector from a scalar is that the vector has a magnitude and a direction, and the scalar has a magnitude and no direction.
So acceleration is a vector.

Vector and Scalar of Acceleration What is the acceleration vector or scalar,

Acceleration is a vector.
The magnitude of acceleration is a scalar
The sign before acceleration just indicates the direction and has no real meaning

Isn't it said that the average value of a vector must be a vector and its rate of change must be a vector? So why is instantaneous velocity a vector and instantaneous velocity a scalar? If the problem, just began to preview the high school work,

Speed refers to size and direction, so it's a vector Speed means size, no direction. So it's a scalar.

Speed means size and direction, so it's a vector. Speed means size, no direction. So it's a scalar.

Do you know if the instantaneous velocity is a scalar or a vector

Instantaneous velocity is a vector and instantaneous velocity is a scalar

Is the instantaneous velocity a scalar or a vector?

Speed is a vector, so is instantaneous speed
Rate is scalar, and instantaneous rate is also scalar

Triangle of vector triangular force What's the difference between them? A triangle that exerts force in a physical three-force equilibrium? Or a vector triangle? Is it end-to-end? Triangle of vector triangular force What's the difference between them? A triangle that exerts force in a physical three-force equilibrium? Or a vector triangle? Is it end to end?

Basically, the difference is that the triangle of force indicates that the object is in equilibrium under the action of three property forces, and the resultant force of the property force is zero. After the vector force is translated, it can form a vector triangle connected with each other. However, the vector triangle does not necessarily mean that all three vectors are forces, or may be displacements. The range of expression is wider.
