But so many of our physics equations only work in one dimension. So what do we do? We break vectors into x and y components. We look at the motion in the x-direction and the motion in the y-direction separately. A vector is a quantity that has both magnitude (numerical size) ...

It is convenient to have an object (the iterator) that does the operation you want (like sequential access) rather than you writing the details yourself (the "details" being the code that does the actual accessing of the elements of the vector). You should notice that in the for-loop you...
Vectors simplify many of the common tasks you’ll need to do while writing a physics engine. Not only does linear algebra eliminate having to solve separate dimensions separately, it also helps you abstract away from “2D vs 3D” (because you’re not using variables like “positionX” and ...
To do this I have decided to create a Point class that stores a point's (x,y) location and strength vectors bx, by at that point. Then the program creates an ArrayList for every point P(x,y) within the screen's dimensions and calculates the x and y vectors at every...
forces, electric fields, acceleration, displacement. can you have vectors with more or less than 3 elements? yes. in introductory physics courses, it is common to just look at vectors with only 2 dimensions (x and y) just to make things simpler. also, you can have 4 or 5 or even ...
In physics problems involving motion, you treat horizontal and vertical velocities as two separate, independent quantities. Identifying the Horizontal Velocity The horizontal velocity of a motion problem deals with motion in the x direction; that is, side to side, not up and down. Gravity, for ex...
think about forces and torque. you can exert a force on an object just by pushing it with your finger. but what does a force actually do? if you take all of the forces on an object and add them together (as vectors) then this net force changes the velocity of that object. now, ...
The "×" here implies a special kind of multiplication between vectors, as torque is the cross product of radius and force. The direction of the torque vector is perpendicular to the plane formed by the direction of the force vector and the direction of the lever arm, which have an...
In all formulas, tt would then be supplied as the time since braking started, and the result can be split into the corresponding x, y, and z components according to the normalized speed vectors of your moving object. Share Follow edited Mar 13 at 11:19 liggiorgio 4,88566 g...
