One way of expressing the relationship between force and acceleration is the following equation: A=F/M Were A is acceleration, F is force, and M is mass. If we double th…e force and assume that the mass is constant... 2F/M = 2A Which means that when the force is doubled, the acceleration is doubled. (MORE)

The driving force is explained by two factors: voltage gradient and concentration gradient. When there are more ions inside of a cell than outside of a cell, the concentration… gradient is pushing the ion to exit the cell. This is simple diffusion. If that ion carries a negative charge then it also wants to exit the cell because the outside environment is slightly more positive. So if you add both voltage gradient and concentration gradient you get the driving force. In the example above both gradients are pushing the ion outside of the cell. Sometimes you can have the gradients going in opposites and then the driving force will be determined on which gradient is stronger. (MORE)

Triangles are used because if you have a triangle you can use the cosine and sine rules. Since you're asking this question you're probably a student all question will be of th…at form because it's easy for textbooks and teachers.There is also I believe a parallelogram rule but I'm only a student too so i haven't learnt it.

If the force is doubled (assuming mass stays the same) the acceleration doubles as well

1) Graphically. Draw an arrow for the force, and measure the vertical and horizontal components. 2) Use trigonometry. The x-component is the length of the vector times the c…osine of the angle, while the y-component is the length of the vector times the sine of the angle. 3) Use the polar-to-rectangular conversion on your scientific calculator. This is the fastest method, but the details are a bit complicated (since the calculator needs to return two values), and vary from one calculator to another. Check your calculator's manual. (MORE)

You would use trigonometry for that. If, for example, you have a force of magnitude 10 at an angle of 30 degrees: * The x-component is 10 times the cosine of 30 degrees * T…he y-component is 10 times the sine of 30 degrees Or better yet, learn to use the polar-->rectangular conversion on your scientific calculator.
