Two physical quantities used to describe the motion of an object?
Some of the more basic measurements of an object we can take are time and position (or distance). From these values we can calculate things (like speed and direction) that we use to describe its motion.
What are the three equations of motion which of them describe velocity time relation?
The three equations of motion are: ( v = u + at ) (relates initial velocity, acceleration, and time) ( s = ut + \frac{1}{2}at^2 ) (relates initial velocity, acceleration, and displacement) ( v^2 = u^2 + 2as ) (relates initial and final velocity, acceleration, and displacement) The first equation, ( v = u + at ), describes the relationship between velocity and time.
How do you find the velocity of a wave with a frequency of 6 Hz and a wavelength of 2 m?
To find the velocity of a wave, you can use the formula: velocity = frequency x wavelength. In this case, the velocity would be 6 Hz x 2 m = 12 m/s.
How do you find change in velocity?
Change in velocity is found by subtracting the initial velocity from the final velocity. Mathematically, it can be expressed as Δv = vf - vi, where Δv is the change in velocity, vf is the final velocity, and vi is the initial velocity.
What are the equations of motion involving uniform acceleration?
The equations of motion involving uniform acceleration are: v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, t is the time taken. s = ut + (1/2)at^2, where s is the displacement. v^2 = u^2 + 2as, where s is the displacement. These equations describe the relationships between initial velocity, final velocity, acceleration, displacement, and time during motion with uniform acceleration.
How do you calculate acceleration from velocity?
There are 3 formula 1. Final velocity = starting velocity + (acceleration)(time) 2. Final velocity^2 = starting velocity^2 + 2(acceleration)(distance) 3. Distance = (starting velocity)(time) + 1/2(acceleration)(time^2) Use whichever you can use.
What two things do you need for velocity?
The 2 things are speed and distance.

What could describe an airplane's velocity?
The main two useful velocity measurements are... 1. KTAS- Knots (True Airspeed) 2. KIAS- Knots (Indicated Airspeed)
What are three things that adverbs describe?
Adverbs for me only describe 2 thing they describe verbs and adjectives.
What are the three equations of motion which of them describe velocity time relation?
The three equations of motion are: ( v = u + at ) (relates initial velocity, acceleration, and time) ( s = ut + \frac{1}{2}at^2 ) (relates initial velocity, acceleration, and displacement) ( v^2 = u^2 + 2as ) (relates initial and final velocity, acceleration, and displacement) The first equation, ( v = u + at ), describes the relationship between velocity and time.
How do you find displacement when you only have acceleration initial velocity and final velocity?
You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
If you have a kinetic energy of 45 j and your mass is 30kg then what is your velocity?
To find the velocity, you can use the equation for kinetic energy: KE = 0.5 * mass * velocity^2. Rearranging the equation gives 45 = 0.5 * 30 * velocity^2. Solving for velocity gives velocity = √(2 * 45 / 30) = √3 = approximately 1.73 m/s.
How you put and in a sentence?
well you usually use and wen ur trying to describe 2 things together.ex: i brought my bag and my shoes on the trip
How do you find the velocity of a wave with a frequency of 6 Hz and a wavelength of 2 m?
To find the velocity of a wave, you can use the formula: velocity = frequency x wavelength. In this case, the velocity would be 6 Hz x 2 m = 12 m/s.
What 2 things must you know to descriobe the motion of an object?
If movement is in two dimensions: the x-coordinate of the velocity, and the y-coordinate of the velocity. Or alternatively: the magnitude of the velocity, and the direction. If movement is in three dimensions, you need to know three things, for example, x-coordinate, y-coordinate, and z-coordinate of the velocity, or magnitude of the velocity and two components of direction.
How do you find change in velocity?
Change in velocity is found by subtracting the initial velocity from the final velocity. Mathematically, it can be expressed as Δv = vf - vi, where Δv is the change in velocity, vf is the final velocity, and vi is the initial velocity.
