2. Answer the following questions for projectile motion on level ground assuming negligible air resistance (the initial angle being neither 0º nor 90º): (a) Is the acceleration ever zero? (b) Is the acceleration ever in the same direction as a component of velocity? (c) Is the accel...
In two dimensions the motion along the two axes is statistically independent, so that the probability can be factored as: P(x,y,t)=P(x,t)P(y,t), and similarly in three dimensions. Equation (7.1) describes a Gaussian distribution with average position 〈x〉=vt, and with variance 〈x2...
In order to move, the cells adhere and apply forces to their environment. These traction forces can be measured from the deformation of substrates with known mechanical properties (2, 3). Until recently, traction forces were analyzed mostly in two dimensions. The main reasons are that two dimen...

Step 2: Understanding Motion in Two Dimensions (2D) Motion in two dimensions involves movement within a plane. Here, an object can change its direction while still being confined to a flat surface. The motion can be described using two coordinates (like x and y coordinates on a graph). Exa...
