Description: A force of 1 N acts on a body of mass 1 kg, which is able to move freely. Then the body acquires (a) a speed of 1 m s^-1 (b) an acceleration of 1 m s^-2 (c) an acceleration of 9.8 m s^-2 (d) an acceleration of 1.02 m s^-2

step 1 So in this problem, we have a force F that is equals to 1 Newton which is acting on a body of ma

Question

A force of $1 \mathrm{~N}$ acts on a body of mass $1 \mathrm{~kg}$, which is able to move freely. Then the body acquires (a) a speed of $1 \mathrm{~m} \mathrm{~s}^{-1}$ (b) an acceleration of $1 \mathrm{~m} \mathrm{~s}^{-2}$ (c) an acceleration of $9.8 \mathrm{~m} \mathrm{~s}^{-2}$ (d) an acceleration of $1.02 \mathrm{~m} \mathrm{~s}^{-2}$

   A force of $1 \mathrm{~N}$ acts on a body of mass $1 \mathrm{~kg}$, which is able to move freely. Then the body acquires
(a) a speed of $1 \mathrm{~m} \mathrm{~s}^{-1}$
(b) an acceleration of $1 \mathrm{~m} \mathrm{~s}^{-2}$
(c) an acceleration of $9.8 \mathrm{~m} \mathrm{~s}^{-2}$
(d) an acceleration of $1.02 \mathrm{~m} \mathrm{~s}^{-2}$

Step 1

We can use Newton's second law of motion to find the acceleration $a$ of the body. Newton's second law states that the force acting on an object is equal to the mass of the object multiplied by the acceleration of the object, or $F = ma$. Show more…

Key Concepts

Newton's Second Law of Motion

This principle states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). It is fundamental in determining how forces affect the motion of objects.

Acceleration

Acceleration is the rate at which an object's velocity changes over time. It results from the net force acting on an object and is calculated by dividing the force by the mass, illustrating the direct relationship established by Newton's Second Law.

Force

Force is any interaction that, when unopposed, changes the motion of an object. It is a vector quantity with both magnitude and direction, and its effects are analyzed using Newton's laws of motion.
