How to find average acceleration from velocity time graph

The average acceleration is the slope of the graph found as

Explanation:

Here we have

The formula for acceleration is derived as follows

v₁ = v₂ + at which is similar to the equation, y = mx + c, such that the acceleration, a, is the slope and u is the y intercept

average acceleration, a = (v₁-v₂)/(time for the change)

or

So to find the average acceleration, you take two points on the line graph with y coordinates v₁ and v₂ and their corresponding x coordinates t₁ and t₂and plug in the values into the following equation

.

Explanation:

The average acceleration over a certain time interval tells us by how much the velocity changes per time unit over that interval.

The slope or rise over run of a velocity-time graph tells us about the average acceleration.

it doesn't. it was imagined up in the middle ages.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
