Kindly solve it if you know otherwise LEAVE .​

Answer 1

Answer:

1. Lenght = meter (m)

2. Area =m²

3. Volume =m³

4. Mass =kilogram (kg)

5. Time = second (s)

6. Speed=(meter per second) $\frac{m}{s}$

7. Velocity =(meter per second) $\frac{m}{s}$

8. Acceleration =meter per second squared m/s²

9. Velocity Time Graphs = m/s/s.

10. Distance Time Graphs = metre(m)

11. Density=kg/m³

12. Weight = kilogram(Units of Mass (Weight)

13. Force =Newton(N)

14. Gravity= Newtons Per Kilogram(N/kg)

hope it helps ☺️

Answer 2

Length:

•The Basic Unit for Length is meter.

•Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

Area:

•Area is measured in square kilometres (km 2), square metres (m 2), square centimetres (cm 2) and square millimetres (mm 2).

•To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Volume:

•A unit of volume is a unit of measurement for measuring volume or capacity, the extent of an object or space in three dimensions. Units of capacity may be used to specify the volume of fluids or bulk goods, for example water, rice, sugar, grain or flour.

•Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

Mass:

•unit of mass is kilogram.

•these three formulae of mass are the most common ones.

m=ρV

m=W/g

m=F/a

Time:

•the 3 units of time:

1.Second

2.minute

3.hour

•To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

Speed:

•The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph).

•formula of speed is S = d/t

s = speed

d = distance traveled

t = time elapsed

Velocity:

•The SI unit of velocity is metre per second.

•formula of velocity in attachment ☺️

Acceleration :

•The SI unit of acceleration is metres/second2 (m/s2).

•There are two formulas for acceleration.

first formula:-

F= ma

Over here:

F refers to the force

m is the mass

a is the acceleration

second formula in the 2nd attachment☺️

Velocity Time Graphs:

•the slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.

•If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s. If the object is moving with an acceleration of -8 m/s/s, then the slope of the line will be -8 m/s/s.

Distance Time Graphs :

•The standard unit is the 'metre'.

•If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

Density:

• unit of destiny is kilograms per cubic metre.

•p=m/v

where,

p = density

m = mass

V = volume

Weight:

•the SI unit of weight can be measured in kg⋅m/s2 (kilograms times meters per second squared) which is equal to a newton (N).

•The formula for calculating weight is F = m × 9.8 m/s2, where F is the object's weight in Newtons (N) and m is the object's mass in kilograms.

Force:

•The SI unit of force is the newton, symbol N.

• F=ma

Where,

m = mass

a = acceleration

gravity:

•unit of gravity is (N/kg).

•The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.
