Kinematic Equation 2 is used to calculate average velocity by considering the final velocity, initial velocity, acceleration, and time. On the other hand, Kinematic Equation 3 is used to determine the distance traveled by an object, taking into account the final velocity, initial velocity, acceleration, and time.
The variables in Kinematic Equation 2 and their meanings are:
1. v: This represents the final velocity of an object.
2. u: This represents the initial velocity of an object.
3. a: This represents the acceleration of the object.
4. t: This represents the time taken for the object to reach the final velocity.
These variables are related to calculating average velocity through the equation:
Average velocity = (Final velocity + Initial velocity) / 2
By substituting the values of final velocity (v), initial velocity (u), and time (t) into Kinematic Equation 2, we can solve for average velocity. The acceleration (a) does not directly affect the calculation of average velocity.
Now, let's break down the variables in Kinematic Equation 3 and their importance in determining distance:
1. v: This represents the final velocity of an object.
2. u: This represents the initial velocity of an object.
3. a: This represents the acceleration of the object.
4. s: This represents the distance traveled by the object.
Kinematic Equation 3 is used to calculate the distance traveled by an object, given its initial velocity, final velocity, acceleration, and time taken. The equation is as follows:
Distance (s) = (Final velocity (v) + Initial velocity (u)) * Time (t) / 2
By substituting the values of final velocity (v), initial velocity (u), and time (t) into Kinematic Equation 3, we can solve for the distance traveled (s) by the object.
