Acceleration

The concepts of this lesson will allow you to: Explain the terms that are associated with motion and acceleration. Analyze acceleration problems and how to solve them. Identify formulas to calculate acceleration of an object.

Acceleration Terms Discuss and Reviews Velocity Constant or uniform Acceleration Average acceleration Initial velocity Instantaneous acceleration Final velocity

What is Acceleration? How do you calculate it? Acceleration is the change in velocity. Acceleration can be positive or negative. Negative acceleration is called deceleration. Acceleration can be calculated by taking the change in velocity over the change in time.

Acceleration Example If your BattleBot starts from rest and travels up to 1 m/s in 4 seconds, what is your BattleBot’s acceleration? v 1 = 0 m/s v 2 = 1 m/s t 1 = 0 s t 2 = 4 s a = ? Define the known and unknowns Use the right formula Substitute in known values 0.25 m/s 2 Solution The BattleBot’s velocity changed 0.25 m/s every second within the time interval

Kinematics Equations Kinematics is a branch of physics that studies motion. With these equations and what we now know about distance, time, velocity and acceleration we can calculate any of these if unknown. Notice on the right side the variable that is not in the equation to the left. This helps in determining the right equation. dd a VfVf ViVi tt
