Distance Catch Up

Calculates the amount of time that it takes for a person traveling at one speed to catch a person traveling at another speed when one person leaves at a later time.

Distance Rate and Time

Solves for distance, rate, or time in the equation d=rt based on 2 of the 3 variables being known.

Falling Object

Calculates any of the 3 items in the falling object formula, distance (s), acceleration (a), and time (t).

Gravitational Force

Using Sir Isaac Newtons Law of Gravitational Force, this calculator determines the force between two objects with mass in kilograms at a distance apart in meters using the constant of gravity.

Line Equation-Slope-Distance-Midpoint-Y intercept

Enter 2 points, and this calculates the following:

* Slope of the line (rise over run) and the line equation y = mx + b that joins the 2 points

* Midpoint of the two points

* Distance between the 2 points

* 2 remaining angles of the rignt triangle formed by the 2 points

* y intercept of the line equation

* Point-Slope Form

* Parametric Equations and Symmetric Equations

Or, if you are given a point on a line and the slope of the line including that point, this calculates the equation of that line and the y intercept of that line equation, and point-slope form.

Also allows for the entry of m and b to form the line equation

Opposite Direction Distance

Word Problem calculator to measure distance between 2 people moving in opposite directions with rate and time solved for as well

Point and a Line

Enter any line equation and a 2 dimensional point. The calculator will figure out if the point you entered lies on the line equation you entered. If the point does not lie on the line, the distance between the point and line will be calculated.

Rebound Ratio

Calculates a total downward distance traveled given an initial height of a drop and a rebound ratio percentage
