please bhi lpg spam send mat kar nai plz​

Answer 1

Explanation:

velocity-: 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

Speed-:In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position; it is thus a scalar quantity

mass-:Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force

volume-:Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

density-: Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance

diameter-: a straight line that goes from one side to the other of a circle, passing through the centre

Answer 2

1.DEFINE VELOCITY

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)

2. DEFINE SPEED

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. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.

There are four types of speed and they are:

There are four types of speed and they are:Uniform speed.

There are four types of speed and they are:Uniform speed.Variable speed.

There are four types of speed and they are:Uniform speed.Variable speed.Average speed.

There are four types of speed and they are:Uniform speed.Variable speed.Average speed.Instantaneous speed.

3.DEFINE MASS

Mass is a measure of the amount of matter in an object. ... Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it. An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity.

4.DEFINE VOLUME

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

5.DEFINE DENSITY

Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water)

6.DEFINE DIAMETER

a straight line passing through the center of a circle or sphere and meeting the circumference or surface at each end. a straight line passing from side to side of any figure or body, through its center

Diameter of a circle

Diameter of a circle The diameter is the length of the line through the center that touches two points on the edge of the circle.
