Question

calculate the accelereation of a body of 250g when acted by a force of 1 N​

Answer 1

Answer:

1kg=1000g

250g=0.25kg

Force=ma

a=force /mass

1/0.25

100/25

4m/s^2

Explanation:

Answer 2

Given :-

• Mass (m) = 250 g
• Force (F) = 1 N

To find :-

• Acceleration = ?

Solution :-

• Firstly, convert mass from g into kg. [ Both the units should be same ]

• 1 kg = 1000 g

= $\sf\dfrac{250}{1000}$

$\sf{=~0.25~kg}$

As we know,

• $\sf{F~=~ma}$

So,

• $\sf{Acceleration~=~\dfrac{Force}{Mass}}$

Put the given values :-

= $\sf\dfrac{1}{0.25}$

= $\sf\dfrac{100}{25}$

= $\sf{4~{ms}^{-2}}$

• Acceleration = 4$\sf{{ms}^{-2}}$

Newton :-

• When a body of mass 1 kg, moves with an acceleration of $1 m/s^2$, then the force acting on the body is called one newton.
• 1 newton (N) = 1 $\sf{{kgms}^{-2}}$

Acceleration :-

• The rate of change of velocity of a body is called Acceleration.
• Its S.I. unit is $\sf{{ms}^{-2}}$
