Free Body Diagrams and Net Force
Free body diagrams are vector diagrams that show all forces acting on a single object. When creating these diagrams, you must properly label each force to track what's happening. This visual tool makes complex physics problems much easier to solve.
When analyzing forces, remember that equilibrium occurs when net force equals zero. This means the object is either motionless or moving at a constant velocity (no acceleration). When the net force isn't zero, the object must be accelerating—either speeding up or slowing down.
To determine net force in multiple dimensions, consider each dimension separately. For example, add all x-direction forces together, then all y-direction forces, and finally combine them using the Pythagorean theorem if needed. Remember the formula: net force = mass × acceleration.
Physics Tip: When solving problems, draw the free body diagram first! This visual representation helps you identify all forces and their directions before calculating anything.

Determining Net Force in Different Views
When analyzing forces from different perspectives, always break them down by direction. In a top view problem, separate x and y components before calculating the net force in each direction.
For objects on flat surfaces viewed from the side, remember that the total vertical force equals zero when an object isn't moving up or down. This means the normal force from the surface perfectly balances the gravitational force.
To find the resultant (net) force when forces act in multiple directions, use the formula R = √ where x represents the net force in the horizontal direction and y represents the net force in the vertical direction. This gives you both the magnitude and direction of the total force acting on the object.
Quick Check: If an object isn't accelerating, the net force must be zero, even if multiple forces are acting on it. This is a key concept for solving equilibrium problems!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
