Uniformly Accelerated Motion (UAM)
Uniformly Accelerated Motion is defined as motion where the acceleration remains constant. This indicates that the object's velocity changes at a uniform rate over time. In UAM, since the acceleration does not fluctuate, it simplifies the analysis and calculations associated with motion.
-
Constant Acceleration: The acceleration remains unchanged over time.
-
UAM Equations: There are specific formulas to calculate the position and velocity of the moving object.
-
Practical Applications: Applicable across various industries like automotive and aerospace for optimizing vehicle performance.
Position-Time Equation
The position-time equation outlines the location of an object in uniformly accelerated motion as related to time. This equation is represented by: S = S0 + V0t + (1/2)at², where S stands for the final position, S0 is the initial position, V0 is the initial velocity, a is the acceleration, and t is the time.
-
Initial Position (S0): The starting point of the object.
-
Initial Velocity (V0): The velocity at the initial moment.
-
Acceleration (a): The rate at which velocity changes.
-
Time (t): The time interval being measured.
Velocity-Time Equation
The velocity-time equation connects the velocity of an object in uniformly accelerated motion with time. The formula is: V = V0 + at, where V signifies the final velocity, V0 is the initial velocity, a is the acceleration, and t is the time.
-
Initial Velocity (V0): The velocity at the onset of motion.
-
Acceleration (a): The rate of change of velocity.
-
Time (t): The duration during which the object accelerates or decelerates.
-
Final Velocity (V): The velocity of the object after time t.
