According to Newton's second law, how are acceleration and mass related? Directly or indirectly when force is constant?

1 answer:

4 0

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

If the amount of work done was 6 joules on an object and the object was moved 30m,

Nonamiya [84]

Answer:

180

Explanation:

Work done= Force x distance

<u>So rearrange the formula to find the force</u>

Force= Work done/distance

Force= 6/30

Force= 1/5 N or 0.2 N

Which is the best reason a writer would use a unreliable narrator

avanturin [10]

Answer: Explanation:

Authors sometimes use an Unreliable Narrator to tell the story, a protagonist who can't be trusted to tell the events accurately. Either they are insane, evil, delusional, forgetful, or just plain wrong... whatever their reasons, the writer uses this technique to 'hook' the reader.

Please someone derive 3rd equation of motion u- v= 2sa

zlopas [31]

We know

$\\ \sf\longmapsto a=\dfrac{dv}{dt}$

$\\ \sf\longmapsto a=\dfrac{dv}{dx}.\dfrac{dx}{dt}$

$\\ \sf\longmapsto a=v\dfrac{dv}{dx}$

$\\ \sf\longmapsto adx=vdv$

Integrate

$\\ \sf\longmapsto a{\displaystyle{\int}^x_{x_0}}dx=\displaystyle{\int}_u^v vdv$

$\\ \sf\longmapsto a(x-x_0)=\dfrac{v^2-u^2}{2}$

Here

x-x_0=s

$\\ \sf\longmapsto v^2-u^2=2as$

What is the difference between velocity and acceleration and how do we find each one

katen-ka-za [31]

You know how speed is how fast distance changes ?

Well, velocity is speed PLUS the direction of the motion,
and acceleration is how fast velocity changes.
