Newton’s Second Law:
- The rate of change of linear momentum of a body is directly proportional to the external force applied on the body and this change takes place always in the direction of the applied force.
- If a body of mass m moves with velocity then its linear momentum can be given by and if force is applied on a body, then
\(∴ \vec F = m\vec a\)
Where F = Force, m = mass and a = acceleration
CALCULATION:
Given – F = 10 N and a = 5 m/s2
According to the second law of motion,
Force = mass × acceleration
Substituting the value in the formula
F = m × a
10 = m × 5
m = 10/5 = 2kg
Hence, mass of the body is 2 kg
