Kinematic Equations and Graphs The goal of this first unit of The Physics Classroom has been to investigate the variety of means by which the motion of objects can be described. The variety of representations that we have investigated includes verbal representationspictorial representationsnumerical representations, and graphical representations position-time graphs and velocity-time graphs. In Lesson 6, we will investigate the use of equations to describe and represent the motion of objects. These equations are known as kinematic equations.
Solve this formula for the height. So just to visualize this a little bit, let me draw a triangle here. Let me draw a triangle just so we know what b and h are.
So this distance right over here is b. And then this distance right here is our height. That is the height of the triangle-- let me do that at a lower case h because that's how we wrote it in the formula.
Now, they want us to solve this formula for the height. And we want to solve for h. We essentially want to isolate the h on one side of the equation. It's already on the right-hand side. So let's get rid of everything else on the right-hand side.
So we can do it-- well, I'll do it one step at a time. We could kind of skip steps if we wanted to. So let's do that.
So let's multiply-- remember anything you do to one side of the equation, you also have to do to the other side of the equation. Now, what did this do? So on the right-hand side of the equation, we're just going to have a bh. And on the left-hand side of the equation, we have a 2A.
And we're almost there, we have a b multiplying by an h.
If we want to just isolate the h, we could divide both sides of this equation by b. We're just dividing both sides. You can almost view b as the coefficient on the h. We're just dividing both sides by b. And then what do we get? Well, the right-hand side, the b's cancel out.
On the left-hand side, we're just left with 2A over b. So we get h-- and I'm just swapping the sides here.

We have solved this formula for the height. And I guess this could be useful. If someone just gave you a bunch of areas and a bunch of base lengths, and they said keep giving me the height for those values, or for those triangles.Home > Formulas > Formulas: Physics Formulas and Math Formulas.

Physics Formulas on laws of motion, one, two and three dimensional motion, work, energy, power, circular motion, gravitation, properties of matter and electricity. Also tutorials and answers on many physics topics. In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force.
For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement).
