Simplifying the integral results in the equation v(t) = -9.8t + C_1, where C_1 is the initial velocity (in physics, this the initial velocity is v_0). This means that for every second, the velocity decreases by -9.8 m/s. To find the position equation, simply repeat this step with velocity.
Velocity describes how position changes; acceleration describes how velocity changes. Two layers of change!

Instantaneous speed is a measurement of how fast an object is moving at that particular moment. Instantaneous velocity is a vector quantity that includes both the speed and the direction in which the object is moving. Learn how to find an object’s instantaneous speed or velocity in three ways - by using calculus, by looking at the slope of a given point on a graph of an object’s rate vs ...
In this video David shows how to determine the equation of a wave, how that equation works, and what the equation represents.
Let's derive the drift velocity formula (v = eEt/m), in terms of relaxation time. Drift velocity is the average velocity with which, the electrons drift in the opposite direction of the field. We start with the acceleration of the electrons, a = F/m = eE/m.
Let's say a 1,000 kilogram car starts from rest and takes 2 seconds to reach a speed of 5 meters per second. We can find the power output by the engine by taking the work done on the car divided by the time it took to do that work.
