What Happened to Physics Class? A Teacher’s Perspective on How It’s Changed
The other day, I put a small, wooden block on a ramp in front of my ninth-grade physics class and asked a simple question: “What do you think will happen when I let go?”
A few students immediately tapped away at their laptops, fingers flying across the keys. One student, Maya, looked up with a confident smile. “The coefficient of friction is probably around 0.3, so it will accelerate at a rate of 2.8 meters per second squared.”
I hadn’t given them any numbers. I hadn’t asked for a calculation. I had asked what they thought would happen.
This wasn’t an isolated incident. It’s a scene that plays out in my classroom more and more each year, and it’s left me wondering what, exactly, has happened to physics class. The class I teach today feels fundamentally different from the one I student-taught in fifteen years ago, and it’s not just the technology.
When I was in high school, physics was a messy, hands-on affair. We spent a full week trying to build a paper roller coaster that would keep a marble moving for ten seconds. We spent another two weeks dropping objects from the second-floor landing to test gravity, ignoring air resistance until our calculations were wildly off. We argued about why a spinning bicycle wheel felt so stable. The equations came later, as a way to explain the chaos we had just witnessed. The goal was to build an intuition for how the world worked.
Now, the goal often feels like it’s to get the right answer on a standardized test.
The shift is subtle but pervasive. It’s in the curriculum guides that are packed with content standards and less with process skills. It’s in the pressure to prepare students for AP exams in May, which means by October, we need to be deep into kinematics and Newton’s laws. There’s little time for the luxury of wonder. The frantic pace leaves no room for the marble to jump the track, for the calculations to fail, or for the messy, valuable process of figuring out why.
The technology is a double-edged sword. On one hand, the simulations are incredible. We can model a pendulum on Jupiter or visualize an electromagnetic field in ways that were impossible when I was a student. But it’s a passive kind of learning. Clicking “play” on a perfect digital simulation isn’t the same as feeling the tension in a real string or hearing the clatter of a real block tumbling off a ramp.
The bigger issue is that the simulation provides the answer too quickly. There’s no struggle, no wrestling with a problem. When Maya gave me that friction coefficient, she was doing what she’d been trained to do: find the formula, plug in the numbers, get the answer. She had become a calculator, not a physicist. She had the tools but not the intuition.
I’ve started trying to push back, to carve out small spaces for the kind of physics I remember. It’s not a grand, systemic change, just small adjustments. After the ramp incident, I didn’t just give them the answer. I asked Maya to put her laptop away.
“Let’s forget the equations for a minute,” I said. “I want you to just watch it. Then I want you to predict what will happen if I change the surface to felt, or if I make the ramp steeper.”
We spent the rest of that class period just observing and predicting. We didn’t write a single formula. The students were confused at first. Some were frustrated. “But how do we know if we’re right?” one student asked.
“You’ll know when you see it,” I said.
We talked about the “why.” Why did the felt slow it down more? Why did the steeper ramp make it go faster? Their language was imprecise, full of “it feels like” and “it seems to.” But it was also full of observation and curiosity. It was a small, messy, and deeply human moment of learning.
For parents and caregivers seeing their child struggle with or disengage from physics, this shift is the likely culprit. It’s not that your child isn’t smart enough. It’s that they’re often being asked to run before they can walk. They’re being handed the answers before they’ve had a chance to ask the questions.
So what can you do at home? You don’t need a lab or a textbook. You just need to encourage a different kind of observation. When you’re pushing a grocery cart, ask your child why it’s harder to get it moving than to keep it moving. When you’re playing with a ball, ask them what makes it spin. Don’t ask for the scientific term; ask for their explanation.
Try to separate the “what” from the “why.” The “what” is the calculation, the formula, the answer on the test. The “why” is the curiosity. You can nurture that by simply asking them to predict what will happen next in an everyday situation. Stack the dishwasher differently and ask if it will get the dishes as clean. Change the angle of a garden hose and ask which stream will go farther.
This isn’t to say that the formulas and the math aren’t important. They absolutely are. They are the language of physics. But you have to have something to talk about before you learn a language. You need the experience—the falling block, the spinning wheel, the messy marble run—to give the language meaning. Otherwise, you’re just memorizing vocabulary in a vacuum.
I’m still figuring it out. My classroom is a mix of old-school intuition and new-school calculations. We still have to meet the standards and prepare for the exams. But I’m trying to be more intentional about the balance. I’m trying to build in more time for that initial, quiet observation. It’s a small rebellion against the frantic pace of modern education.
Last week, Maya stayed after class. She was holding the wooden block from the first day. “I think I get it now,” she said. “It’s not just about the numbers. It’s about what the numbers mean.”
It was a small victory, a tiny moment of connection in a system that often feels designed for the opposite. I don’t know if it will be enough. I don’t know if I can really change the tide. But for that one student, for that one afternoon, the physics class felt a little less like a formula and a little more like a way of seeing the world. And for now, that feels like a good place to start.
