Question

a 1kg object accelerated at a constant rate of 5meter per second square . estimate the net force needed to accelerate the object

Answer 1

Required Answer :

The net force required to accelerate the object = 5 N

Given :

• Mass of the object = 1 kg
• Acceleration of the object = 5 m/s²

To find :

• Net force needed to accelerate the object = ?

Concept :

Here, we are given the mass and acceleration of the object and we need to calculate the net force required to accelerate the object. So, we will directly apply the formula of force which as following ::

• F = ma

where,

• F denotes the force
• m denotes the mass
• a denotes the acceleration

About force ::

★ Force is the product of mass and acceleration.

• It's S.I. unit is newton (N).

Solution :

Calculating the force :-

⇒ Force = ma

⇒ Substituting the given values :-

⇒ Force = 1 × 5

⇒ Force = 5

Therefore, the net force required to accelerate the object = 5 N
