Question

Imagine if Newton's 2 nd law didn't work and that forces cause unpredicatble accerlations, What mght happen if you swing a bat at a baseball?

Answer 1

Newton's second law details the relationship between the applied force, the mass and its acceleration.

This can be expressed mathematically as -

F = m*a

Mass 'm' is constant.

So,

F a

Means, acceleration is directely proportional to the applied force.

Now, if Newton's second law didn't work and force cause unpredictable accelerations, then -

When we swing a bat at a baseball, it will cause INFINITE acceleration to the baseball.

Because, in this case acceleration(a) is not proportional to the applied force (F).
