Lesson: Acceleration over Distance and Time High School PhysicsPhysics
In this lesson, we will learn how to calculate acceleration using an object’s initial velocity, its displacement, and its acceleration time using the formula s = ut + ½at².
Sample Question Videos
A car that was initially moving at a steady speed travels a distance of 15 m while accelerating in a straight line for 10 seconds at 2.5 m/s2 in the opposite direction to its original velocity. What was the car’s initial speed?
An object has an initial velocity of 12 m/s. The object accelerates at 2.5 m/s2 in the same direction of its velocity for a time of 1.5 s. What is the displacement of the object during this time? Answer to one decimal place.
An object has an initial velocity of 10 m/s. The object accelerates at 1.5 m/s2 in the opposite direction to its velocity for a time of 2.5 s. What is the net displacement of the object in the direction of its initial velocity during this time? Answer to one decimal place.
