Explanation:

Scalar amounts are characterized by a magnitude through no applicable direction. In contrast, vector quantities must have both magnitude and also direction that action.

You are watching: Which one of the following is a vector quantity?

The product that a vector quantity and also a scalar quantity will always be a vector quantity. Force results native the product of fixed (scalar) and also acceleration (vector). Load is a type of force, produced by the acceleration that gravity.

Voltage is a scalar quantity and also can be calculated by the product of existing (scalar) and also resistance (scalar).

Work is a vector quantity and can be calculated by the product the a force (vector) and also displacement (vector).

Velocity is a vector and can it is in calculated through the quotient the displacement (vector) every unit time (scalar).

Explanation:

Scalar quantities are identified by a magnitude through no applicable direction. In contrast, vector quantities must have actually both magnitude and also direction the action.

Speed is defined by a change in street per unit time. Since distance and also time space both scalar quantities, the resulting speed is additionally scalar. In contrast, velocity is offered by a change in displacement every unit time. Since displacement is a vector, the resulting velocity is likewise a vector. The magnitude of a offered speed and also given velocity might be equal, yet the velocity term will represent the speed used in a particular direction.

Acceleration is a vector quantity determined by a adjust in velocity every unit time. Load is produced by the pressure of heaviness on an object; all pressures are vectors.

Explanation:

Scalar amounts are characterized by a magnitude with no applicable direction. In contrast, vector quantities must have actually both magnitude and direction of action.

Some common scalar quantities are distance, speed, mass, and time. Some typical vector amounts are force, velocity, displacement, and acceleration.

Explanation:

A vector has both magnitude and direction, while a scalar just has actually a magnitude. When asking if something is a vector or a scalar, asking if a direction would certainly make sense -- in this case, force is the just vector. When a direction would aid with speed and distance, those room both scalars; the vector version of rate is velocity, and the vector variation of distance is displacement.

Explanation:

A scalar quantity deserve to be characterized by magnitude alone, if a vector quantity should be identified by both magnitude and also direction of action.

Of the given answer options, mass if the just scalar quantity. Mass has actually magnitude, normally in kilograms, yet cannot act in a direction. "7kg west," because that example, is nonsensical.

In contrast, displacement, velocity, force, and momentum need to be applied in a given direction. Displacement is the vector identical of the scalar amount distance, and velocity is the vector equivalent of the scalar quantity speed. Forces must always act in a offered direction, and also have no scalar equivalent. Similarly, momentum must constantly be directional.

A son skates approximately the leaf of an ice rink and also finishes specifically where she started. If the rink has a radius of

, what is the total displacement that the skater?Explanation:

There is a unique and an important difference in between measuring displacement and measuring distance. Distance is a scalar quantity, which way that it depends on the route taken and is live independence of the direction traveled. Distance actions the full length traveled, without any reference to the beginning point.

In contrast, displacement is a vector quantity. This means that both the magnitude of the length and also its direction need to be factored into the calculation. Displacement is essentially the net distance traveled in relationship to the beginning point, independent of the route traveled.

In this question, the ska finishes in specifically the same place that she started. Without any kind of other information, we can conclude the her displacement is zero. That does not issue what path she take it to return to her starting point; she could have taken one action forward and also one step back, skated the entire rink seventeen times, or merely jumped and also landed. Every one of these possibilities would an outcome in zero displacement.
