Why Do Students Struggle With Newton’s Laws 2025
Book Answer (The Proper Textbook Version)
Newton’s Laws of Motion describe the relationship between the motion of an object and the forces acting upon it. These laws are:
- First Law (Law of Inertia): An object remains at rest or moves in a straight line at constant speed unless acted upon by a net external force.
- Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is expressed as F = ma.
- Third Law: For every action, there is an equal and opposite reaction.
These laws form the foundation of classical mechanics and are essential in understanding how objects move under various force interactions.
The Real Talk: Why Newton’s Laws Drive Students Nuts
Alright, let’s be real. Newton’s Laws might look all clean and logical on paper, but the moment you’re thrown into a physics problem? Chaos. Here’s why students find this topic painfully confusing — and how to make sense of it.
1. It Sounds Too Simple (Until It Isn’t)
“An object in motion stays in motion…” Cool, right? Until your brain goes: wait, why does a ball slow down when I throw it? Shouldn’t it just keep going? Textbooks say “net force,” but gravity, friction, and other invisible forces mess with your understanding right from the start.
What’s happening: You’re trying to picture ideal physics in a non-ideal world full of friction, air resistance, and annoying reality. The First Law is pure, but the real world adds complexity.
2. Free Body Diagrams = Brain Meltdown
Let’s be honest — drawing those arrows, labeling forces, figuring out what’s acting where? It can feel like assembling IKEA furniture without the manual.
Why it’s confusing: Most students don’t get enough practice identifying forces. They memorize problems instead of really “seeing” the push, pull, or tension in each scenario.
Fix it: Break it down. One object. One set of forces. Build slowly.
3. Second Law (F = ma) Looks Easy but Acts Sneaky
“Force equals mass times acceleration” — sounds manageable until your teacher starts throwing in elevators, inclines, pulleys, and friction. Suddenly you’re lost in variables and directions.
Here’s what actually helps: Realizing that F = ma isn’t a formula to plug into — it’s a way of thinking. What force is acting? What’s it doing to the motion? Don’t rush to solve; understand the story first.
4. Third Law = The Big Plot Twist
You push a wall. It pushes you back. So why aren’t you flying across the room? This law just messes with intuition.
The trick: Third Law pairs happen between different objects. When you push the wall, it pushes back on you — but your feet push on the floor, and friction keeps you grounded. Students struggle because they think both forces act on the same thing.
Once you get this: mind = blown.
5. Too Many Words, Not Enough “Feel”
Textbooks often throw a bunch of definitions at you. But Newton’s Laws are best learned with motion — pushing stuff, sliding books, tossing balls.
Most students struggle because they don’t “feel” the laws in action. We read about them but don’t interact with them. That’s why physics labs or watching slow-motion videos of collisions can suddenly make the laws click.
Let’s Make It Super Easy (The Fun Explanation)
Still confused? Here’s Newton’s Laws in ultra-simple, human-brain-friendly words:
- Law 1: Things like to chill how they are. You gotta force them to change.
- Law 2: The harder you push, the more it moves — unless it’s super heavy.
- Law 3: Punch a wall? It punches back. Physics doesn’t care about your feelings.
Boom. You just did Newtonian mechanics.
Want to practice? Next time you’re in a car and it suddenly stops — notice how your body wants to keep going? That’s the First Law. And your seatbelt is the external force stopping you. You’ve lived physics.

Final Word
Newton’s Laws aren’t hard because they’re impossible — they’re hard because they require a shift in how we understand motion. It’s not about memorizing formulas; it’s about observing the forces all around us and figuring out how they act.
