Welcome to our Physics lesson on Case 4 - Reference point is at rest and the object is moving at constant acceleration, this is the fifth lesson of our suite of physics lessons covering the topic of Relative Motion, you can find links to the other lessons within this tutorial and access additional physics learning resources below this lesson.
Case 4 - Reference point is at rest and the object is moving at constant acceleration a⃗
This case represents the situations described earlier in tutorials involving Physics tutorial motion with constant acceleration. Thus, since v⃗' = 0, we obtain for the position of an object at any instant t (if the object which initially was at x⃗0 and it is moving at constant acceleration a⃗):
Equation 3
x⃗(t) = x⃗0 + v⃗0 × t + a⃗ × t2/2 - v⃗' × tor
x⃗(t) = x⃗0 + v⃗0 × t + a⃗ × t2/2
since v⃗' = 0 and as a result, the last term of equation (3) is cancelled.
