LAW OF ACCELERATION – The Second Law | Newton’s Law Of Motion

LAW OF ACCELERATION – Gotta Go Fast

LAW ACCELERATION – In this topic, we will discuss the second law from Isaac Newton’s Law of Motion: the Law of Acceleration.

LAW OF ACCELERATION

Following up in our continuation with the Laws of Motion, let’s recap the first law. Again it states that:

An object at rest will stay at rest, forever, as long as nothing pushes or pulls on it. An object in motion will stay in motion, traveling in a straight line, forever, until something pushes or pulls on it. “

Now, we will discuss the second law of motion, which states that:

” The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. “

This law can be expressed in the scientific notation:

F = ma

Where:

  • F = force | Unit = Newton (N or kg(m/s 2 )
  • m = mass | Unit = kilograms (kg)
  • a = acceleration | Unit = meters per second square (m/s 2 or m/s/s)

It can also be rearranged to find the acceleration:

a = F/m

Examples:

Find the given:

  • F = 10
  • m = 2kg
  • a= ?

a = F/m

a = 10 kg (m/s 2 ) / 2kg

a = 10m/s 2 / 2

a = 5 m/s 2

  • F = ?
  • m = 4
  • a = 10

F = ma

F = 4 kg (10 m/s 2 )

F = 40 kg(m/s 2) or 40N
