What is Newton’s law of motion?

For every action, there is an equal and opposite reaction. That’s Newton’s law of motion. It means that when you push on something, it pushes back on you. This little bit of physics makes for a complicated balancing act in the middle of a flight during turbulence, but Newton would be proud! So what are some tips for mastering this? newtons law of viscosity relates. Here are eight tips from the Inverse team to go from novice to expert in no time!

1) Fully understand your objects. 

The first step to understanding any phenomenon is properly classifying it and looking at the bigger picture. That’s what Newton did when he figured out that gravity made the planets move. Instead of getting hung up on how it works, or even how to describe it — he took a step back and classified what he saw: an object in motion will continue in motion unless acted upon by an outside force.

2) Apply the third body rule for double pendulums. 

Newton’s first law states that objects at rest tend to stay at rest, and objects in motion tend to stay in motion — except when a second object is involved! Take double pendulums, for example. They’re like Newton’s second law crash test dummies. They react in a unique way. When both pendulums are swinging in the same direction, they’re perfectly balanced. When both are swinging in the opposite direction, they’ll try to tip over. It’s easy to see why this simple test can yield some great insights into what’s happening with your objects or systems.

3) Understand gravity as a speed and not just a force. 

A force is something that pushes an object in one direction, like gravity does on the moon and sun. A speed is something that goes somewhere else — like light does as it travels across space from star to star … or from a star to a planet.

4) Remember acceleration isn’t the same as velocity. 

Acceleration is the rate at which velocity changes. Velocity, on the other hand, is how quickly an object is covering distance, regardless of its direction. You can accelerate without changing speed and slow down or stop without slowing down! When pilots talk about airspeed (velocity) and ground speed (acceleration), they’re talking about this difference.

5) Vary the forces you apply to your object.

Successful pilots understand that changing the force and direction of an object will change its motion. The faster you push your plane, the higher it will go. The faster you pull back on the stick, the more it will tilt to one side. So what determines what happens next? You guessed it: Newton’s third law, that equal and opposite reaction! For example, let’s say your plane is flying straight and level, like an arrow in flight. Try tilting up or down. You’ll see that your plane naturally follows the direction of the nose. The faster you tilt, the faster it will go. However, if you keep pulling back on the stick to follow its natural path and go higher, gravity takes over and it starts sinking.

6) Put two pendulums in motion with a third object.

When things start to get a little more complicated — like when you’re in the cockpit and have several forces working at once–you can use a rope to visualize your forces. Toss one end of some rope with a knot on it out the window, like you would throw an anchor, and grab it from the other side with both hands. Vary the speed at which you pull on each side. You’ll feel a force in both directions. Pull back on one side, and your plane will go up, but if it does, then what’s pulling it down? Let go of one end of your rope, and toss in another knot that is heavier or lighter than the first. It’s hard to see how multiple forces are working together, so oftentimes a third object (like a rope) can help you visualize how it all works.

7) Apply the third body rule to double pendulums again.

I’m sure you will want to try this one in your plane! It’s a classic example of two pendulums reacting to each other like Newton’s second and third laws. When both pendulums are swinging in the same direction, they’re perfectly balanced. But when they start swinging in opposite directions, things get interesting! Now one pendulum is going up while the other is going down. At the bottom, the pendulum that’s going up will go even higher and the one going downward will start to dive. Again, it’s a classic example of Newton’s third law in action.

8) Put your plane into a controlled stall.

Now we’re getting into some advanced maneuvers! A controlled stall is when you want your plane to lose speed as fast as possible while maintaining control of its flight direction. This maneuver only works on aircraft with low stall speeds — usually slower planes like gliders and sailplanes, where pilots can maintain control during this dangerous maneuver. Cutting engine power or pulling back on the throttle in mid-flight will help you put your plane into a controlled stall.

Conclusion:

These are just a few techniques you can use to master Newton’s laws of motion. When you take the time to learn about these fundamental principles, you can bring your understanding of the world into focus and achieve more success in your endeavors. That’s what Newton did when he figured out how gravity works!
