Question

A body of mass 2kg at rest .A force of 20 N acts on the body calculate the acceleration produced in the body

Answer 1

Given

▬▬▬▬▬▬▬▬▬▬▬

⠀⠀⠀Mass (m) = 2 kg

⠀⠀⠀Force (F) = 20 N

▬▬▬▬▬▬▬▬▬▬▬

We Have to Find Acceleration

$\huge \boxed{ \red { \boxed { \bf Force = Mass \times Acceleration }}}$

Substituting the Values

$\dashrightarrow \bf20 = 2 \times a$

$\dashrightarrow \bf a = \cancel\dfrac{20}{2}$

$\dashrightarrow \bf a = 10 \: m \: {s}^{2}$

Therefore, Acceleration = 10m/s²

Additional Information

• A Push or Pull is defined as a Force.

• Newton 3 law's of Motion are :-

1. This law States that Every body remains at rest or in motion until an external Force is applied'
2. This law States that whatever the Force is acting on any body is always equal to the product of it's Mass and Acceleration.
3. This law States that to every reaction there is an equal and opposite reaction(Action & Reaction always acts on different Bodies)

• Newton law of Universal Gravitational states that every particle attracts each other in this universe with a force directly proportional to the product or masses & inversely proportional to the square of the distance between their center's

• Rate of change of Velocity is known as Acceleration.

• Negative Acceleration is known as Retardation.

Important Formulas

• $\bf F = m \times a$

• $\bf v^{2} - u^{2} = 2as$

• $\bf v = u + at$

• $\bf S = ut + \dfrac{1}{2} at^{2}$

Answer 2

Given

• Mass of body (m) = 2kg
• Force (F) = 20 N

To find

• Acceleration produced in the body

Solution

As we know that

➟ Force = mass × acceleration

★ Let the acceleration be " a "

➟ 20 = 2 × a

➟ a = 20/2

➟ a = 10m/s²

Hence,

• Acceleration produced in the body is 10m/s²

Additional Information

• S.I unit of Force is Newton (N)
• S.I unit of acceleration is meter per second square (m/s²)
• S.I unit of mass is kilogram (kg)
• The rate of change in velocity is known as acceleration.
