The second law of Newton is a quantitative expression of the effects that a force can have on a body’s motion. The product of a mass and velocity of a body determine its momentum. p = m × v
Momentum has both direction and magnitude, which is similar to velocity. If a body has a force acting on it, then it can impact the direction, magnitude, or both of the components of momentum.
The formula F = ma can be stated for a body with a constant mass m.
The linear momentum of a body is calculated as follows:
Mv = p
Now, Newton’s 2nd Law of Motion states:
The rate of change in momentum is precisely proportional to force.
dp/dt
F = k dp/dt
F = k d(mv)/dt
F = k md(v)/dt
K ma = F
K = 1 was used in the experiments.
ma = F
