Start by opening the "Maze Game" activity. When you open it you will be presented with the "Arena of Pain". Set it to "practice" and play with the controls. You will find that by clicking in the lower-right box you are able to create a vector which controls the motion of the red dot in the arena. Play around with it. In particular, it has three modes: R, V and A. Figure out what they do. We will only use "practice" mode, but you may find Level 1, Level 2 and Certain Death fun.
(a) Use the "Maze Game" to explore the motion of an object which starts from rest, accelerates to the left and then switches to accelerating down. Sketch a motion diagram for this.
(b) We will now do this slightly more precisely. A spaceship is initially at rest at (230m) j near a set of axes that someone conveniently left floating in space here. It is shown in Figure 1(a) which has a scale of 10 m per square. Reproduce the figure on graph paper. The spaceship accelerates at 20 m/s2 in the x-direction for 3 s. It then stops accelerating in the x-direction and immediately accelerates at 10 m/s2 in the negative y-direction for 4 s. Draw the motion diagram for the spaceship, to scale, on graph paper.
By what percentage should the pressure of a given mass of gas be increased,so as to decrease its volume by 10% at a constant temperature.

Adding 2 Vectors An easy demonstration of adding 2 vectors graphically. Also demonstrates in which vector addition is commutative.
Motion of an object in a plane is known two dimensional (2-D) motions. For 2-D motion acceleration or velocity can be defined by two elements in any two mutually perpendicular dire
Resolution of Forces by Calculation: One vector was resolved into two mutually perpendicular components. So if there are several vectors each can be resolved into two
