Power Rule:
- Multiply the constant by the original power.
- Subtract a power
Examples:
a) The displacement is found by subtracting the final point from the initial point. In order to do this, you must substitute 0 in for t, as well as the time the object is ending of the original equation. Units: meters b) The velocity equation is the derivative of the position or original equation. To find the velocity at a certain time, the value of the time is plugged in for the t value of the velocity equation. Units: meters/second c) The equation for acceleration is found by taking the second derivative of the original equation. First you must find the derivative of the equation, then find the derivative of that equation. Then, in order to find the acceleration at a certain time, plug the value in for t.
