Newton's second law tells us that force is directly proportional to mass and acceleration, such that:

F = m a

Where force is measured in newtons (N).

The three fundamental laws of Newton are:

  • Law of inertia: every body resists change.
  • Force Law: Force equals mass times acceleration.
  • Law of action/reaction: every action will have a particular reaction.

Newton's laws are fundamental to understanding the interaction between bodies. Today they are still valid, although at the atomic level it has some exceptions that quantum mechanics studies.

A 7.5 kg bowling ball would require what force to accelerate it down an alleyway at a rate of 3.2 m/s² down the alley

Data:

m = 7.5 kg

F = ?

a = 3.2 m/s²

The formula to calculate the force is: F = m * a

We clear, but in this case it is not necessary, since we only want to calculate the force.

F = m * a

F = 7.5 kg * 3.2 m/s²

F = 24 N

The force you need to accelerate down the alley is 24 Newtons.
