# How to calculate the vertical force?

### How to calculate the vertical force?

The gravity calculated thanks to the formula P = mg with m the mass of the object and g a vertical force of gravity called the weight of the object. So, if the mass of the object is 1 kilogram, then gravity equals acceleration to the weight of the object.

### How to find the value of H?

To give the value of the parameter hthe function must be written in the canonical form: y=af(b(x−h))+k. y=af(b(x−h))+k. When this is the case, the parameter h is the number to the right of the minus sign in the parenthesis.

### What is shifting?

Gear changes and gear ratios Secondary 3-4 The gear change is the ratio between the rotational speed of the motor component and the rotational speed of the driven component. This ratio depends on the dimensions of the driving member and the receiving member.

### How to calculate a percentage change between two values?

There is another way to calculate a percentage change between two such values. Divide the end value by the start value and multiply by 100. You get a percentage that establishes a direct relationship between the two values, bypassing the concept of absolute variation.

### How to calculate relative variations?

Finally, multiply your result by 100 to get a percentage. Relative variations are always expressed in percentages, because it is more meaningful for everyone. To get a percentage, simply multiply the result obtained by 100. Get this result and add the “%” sign after it.

### How is the variation over time of a value expressed?

In mathematics, the variation over time of a value is most often expressed as a percentage. If it is negative, there has been a fall in value, if it is positive, it is an increase. The percentage change () expresses the ratio of the absolute (gross) change of the value to the starting value.
