Nick Loper maps Newton's three laws onto entrepreneurial behavior. The first law explains inertia and momentum: people remain on the sidelines until a motivating force prompts action, while action itself generates conversations, research, and ideas that keep movement going. The second law connects acceleration to the strength of the force; a sharp rejection or disappointing raise can produce a faster change than mild dissatisfaction. The third law treats every action as producing a reaction. Visible engagement is feedback, but silence is also a reaction that may signal the need to address a more relevant problem. The model converts motivation and market response into a continuous sequence: find the force, act, preserve momentum, interpret the reaction, and adapt.
Origin
Nick Loper created the Three Laws of Side-Hustle Physics by paralleling Newton's laws and illustrating them with a sports photographer whose award was followed by a disappointing raise.
Core principles
- 01An external force often starts action
- 02The strength of a trigger can determine the pace of change
- 03Every action produces feedback, including silence
- 04Momentum creates ideas that inactivity cannot
How to run it
- 1
Find the external force
Name the event, frustration, aspiration, or accountability mechanism strong enough to interrupt inertia.
Pro tip Translate emotional energy from rejection into a constructive target.
Watch out Waiting passively preserves the current state.
- 2
Create motion
Take a concrete visible step such as registering the domain, publishing the profile, or seeking the first client.
Pro tip Choose an action that creates contact with information or customers.
- 3
Compound momentum
Use new conversations and research to surface ideas that were unavailable from the sidelines.
Pro tip Capture emerging ideas without abandoning the current test impulsively.
Watch out Confusing new ideas with progress can scatter your effort.
- 4
Interpret the reaction
Treat engagement, rejection, and silence as responses to the action and ask what each reveals.
Pro tip A lack of readers may indicate that the topic matters more to you than to them.
Watch out Do not label silence as no data.

Apply the feedback
Change the subject, offer, or distribution based on the reaction, then act again.
Watch out Feedback has no value if it never changes behavior.
In the wild
A journalist wins an international sports-photography award, then learns his boss could secure only a three-percent raise. The mismatch between industry recognition and compensation becomes the force that moves him off the sidelines and toward a photography side hustle.
→ A sharp external impact accelerates serious action on an independent business.
Nick writes a personal blog for years, but almost nobody beyond friends and family reads it. He interprets the weak response as feedback that he needs to write about subjects people care about, while retaining the writing and WordPress skills built through practice.
→ An apparently absent reaction becomes a direction for more relevant content.
Common mistakes
Waiting for motivation to appear
Without a deliberate force or action, inertia keeps the idea on the sidelines.
Dismissing silence
No visible engagement is still a reaction and may indicate that the work addresses the wrong subject.
Is it for you?
Best for
Aspiring entrepreneurs who feel stuck before launch or discouraged by weak early reactions.
Not ideal for
People seeking a detailed market-selection or financial-planning method.
From the transcript
“and object at rest is gonna stay at rest and an object in motion is gonna stay in motion until acted upon by an external…”
“once you're in motion we see this over and over again ideas start to pop up that you never would have had”
“for every action there's an equal and opposite reaction”
