Is moment scalar or vector?
Is moment scalar or vector and why? Scalar has magnitude, but no direction. Vector has magitude and direction. Speed is a scalar. The car's speed is 25mi/hr. No direction is mentioned. Velocity is a vector. The car is traveling 25 mi/hr 20º North of East. Velocity is a vector, because it has magnitude and direction Moment has two meanings Moment of inertia = ∑ Mass* raidus^2 This moment measures how difficult it is to rotate an object. This moment is a scalar. Moment can also mean torque. Torque = Force x distance* sinθ (cross product). However torque can be clockwise or counter-clockwise. So torque is a vector.
What does scalar quanity mean?
Scalar quantity is when you have a magnitude but no direction such as speed
What does it mean when we say a vector is scaled?
It means that the direction of the vector is that same as before but the magnitude has been changed - by a scalar factor.
What does it mean to say that momentum is a vector quantity and that energy is a scalar quantity?
In a vector quantity, it is important to specify a direction. In a scalar quantity, it isn't. Vectors (such as force) have a magnitude (size) and a direction (such as North). Scalars have only a magnitude.
What does hjj mean?
Scalar - a variable quantity that cannot be resolved into components. Most of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time represent an amount of time only and tell nothing of direction. Vector - a variable quantity that can be resolved into components. A vectorquantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. Magnitude, or "size" of a vector, is also referred to as the vector's "displacement." It can be thought of as the scalar portion of the vector and is represented by the length of the vector. By definition, a vector has both magnitude and direction. Direction indicates how the vector is oriented relative to some reference axis.

The speed and direction of a moving object is called?
velocityYou mean, Velocity.. Velocity is the rate of change of displacement (position). It is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is speed, a quantity that is measured in meters per second (m/s or ms−1) when using the SI (metric) system.I linked my source.Speed in a specific direction is called velocity.speed is a scalar unit whereas velocity is a vector unit.Speed is the rate of change of position. In vector terms, speed is the magnitude of the velocity. (Velocity is speed and direction; speed is the velocity along a given direction.)
Which quantity of water in SI system scalar or vector?
If you mean the volume, that's a scalar. If you mean the mass, that's a scalar as well.
What do you mean vector quantity?
A vector quantity is a physical quantity that has both magnitude (size or amount) and direction. Examples of vector quantities include velocity, force, and acceleration. This is in contrast to scalar quantities, which only have magnitude.
If you know an objects velocity do you know it's speed Explain?
These two are synonyms. Both speed and velocity are the time derivative of the diplacement. Confusion may come from the fact that these words are sometimes used to describe a scalar quantity and sometimes a vector qty. Proper usage of these would be in the vectorial form, however, it is often used under the scalar form, when direction or orientation is trivial.
Difference with speed and velocity?
Speed is a scalar quantity that measures how fast an object is moving without specifying the direction. Velocity, on the other hand, is a vector quantity that includes both the speed and direction of motion. In other words, velocity gives information about both how fast something is moving and in what direction.
What do you mean by vectare Quantity give example?
A vector quantity refers to a physical quantity that has both magnitude and direction. Some examples of vector quantities include velocity (speed and direction), force (magnitude and direction), and displacement (distance and direction).
