Question

1. EXPLAIN the following terms:
1. Scalar
2. Vector
3. Distance
4. Displacement
5. Speed
6. Velocity​

Answer 1

Answer:

Scalar quantities are defined by a magnitude with no applicable direction. In contrast, vector quantities must have both magnitude and direction of action. Some common scalar quantities are distance, speed, mass, and time. Some common vector quantities are force, velocity, displacement, and acceleration.

For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination

Distance is a numerical measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). The distance from a point A to a point B is sometimes denoted as.

Displacement (symbolized d or s ), also called length or distance, is a one-dimensional quantity representing the separation between two defined points. The standard unit of displacement in the International System of Units ( SI ) is the meter (m). Displacement is usually measured or defined along a straight line.

Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance.

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north

Answer 2

Answer:

1. Scalar

2. Vector

3. Distance

4. Displacement

5. Speed

6. Velocity

the defination of the following terms are as follows

Explanation:

1.Scalar quantity :- The quantity which have only one unit either distance or magnitude

eg :-temperature, length

2. Vector Quantity :- The Quantity which have both Magnitude and distance

eg  Magnetic field, Force

3. Distance :- The path travelled from a distance A and B is Known as distance

4 Displacement:- The shortest distance travelled from A to B is Known as Displacement

5. speed :-Speed is the distance per unit time

                    S=D/T

6 Velocity:- Velocity is displacement per unit time

                   V=D/T
