how to find acceleration with velocity and distance

Comment

We know that acceleration is defined as change in velocity per unit time. So given velocities and time , we can calculate acceleration. Now here we will be checking how to find acceleration with velocity and distance Uniform acceleration motion in one dimension In uniformly acceleration motion , acceleration can be find with velocity and distance using the formula $v^2= u^2 + 2as$ Where v is … Continue reading how to find acceleration with velocity and distance »

how to find acceleration with velocity and time

Comment

Acceleration is defined as change in velocity per unit time. It is a vector quantity and Average acceleration formula is defined as $a = \frac {Final  \; velocity – Initial \; velocity}{ time \;  taken }$ We will look at steps on how to find acceleration with velocity and time in various situation Uniformly Acceleration Motion Acceleration for a object moving in straight line with constant … Continue reading how to find acceleration with velocity and time »

Vertical line test for functions and relation

Comment

A relation is a function if no pair of the relation has the same first elements. On the graph,two points will lie in the same vertical line if and only if the first coordinate of the two points are same. Therefore if a vertical line intesect the Relation graph at two points then it is not a function. This is called the Vertical line test. If all vertical lines intersect a curve at most once then the curve represents a function

What is Acceleration of free fall

Comment

Free fall acceleration A body falling freely is solely acted by Earth Gravitational force. The falling body is accelerated  by the Gravitational force and acceleration due to this gravitational force is called acceleration due to gravity. Acceleration due to gravity values slightly differs at different altitude and surface .For all practical calculation purpose, we take it  approx  9.8 m.s-2 or 10m.s-2 .Direction is always downwards. It … Continue reading What is Acceleration of free fall »
