A negative instantaneous acceleration means the velocity is decreasing. If it is positive, our velocity is increasing. Using Calculus to Find Acceleration Acceleration is measured as the change in velocity over change in time (ΔV/Δt), where Δ is shorthand for “change in”. For example, le...
Most distance problems in calculus give you thevelocity function, which is thederivativeof theposition function.The velocity formula is normally presented as aquadratic equation. You can find total distance in two different ways: with derivatives, or byintegratingthe velocity function over the given i...
This tells you how to find acceleration with velocity and distance. Remember, though, that this only applies to constant acceleration in one direction. Things get a bit more complicated if you have to add a second or third dimension to the motion, but essentially you create one of these equa...

Shear Rate Formula A fluid is "sheared" when different layers of the fluid move past one another. Shear rate describes this velocity. A more technical definition is that the shear rate is the flow velocity gradient perpendicular, or at a right angle, to the flow direction. It poses a strai...
Instantaneous velocity describes the magnitude of velocity at any point and uses the same formula as average velocity. The difference is that it uses a near-zero change in time to minimize the effects of averaging. Another component of velocity is acceleration, which increases (or decreases) veloc...
Thus if you know the mass of the object, you can use algebra to solve for the velocity v by setting _EP (initial) to EK_ at "launch." We can describe the total mechanical energy of such a situation as the sum of kinetic and potential energy. ...
Momentum is a characteristic of a moving body determined by the product of the body's mass and velocity. To determine the differential change in momentum per unit time, Newton developed a new type of math — differential calculus. His original equation looked something like this: F = (m)(...
