Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Everything moves, but relative to what?
Motion is always described relative to a reference point or frame. A car is moving relative to the ground, but at rest relative to its driver. This is the foundation of kinematics.
↳ Without a reference frame, motion has no meaning.
Where are you and how far did you go?
Position is the location of an object relative to a reference point, often denoted by $x$. Displacement is the change in position: $\Delta x = x_f - x_i$. It is a vector quantity, meaning it has both magnitude and direction.
↳ Displacement is the straight-line change in position, not the path length.
Path length vs. straight line.
↳ Distance is scalar; displacement is vector and can be zero even if distance is not.
This topic covers the fundamental concepts of motion in a straight line, including position, displacement, speed, velocity, and acceleration. It introduces the equations of motion for constant acceleration and their grap...

19 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which of the following quantities is a scalar?
BeginnerSpeed
Speed has only magnitude and no direction, making it a scalar. Velocity, displacement, and acceleration are vectors because they have both magnitude and direction.
The slope of a position-time graph gives the:
BeginnerVelocity
In a position-time graph, the slope (Δx/Δt) represents the rate of change of position, which is the velocity of the object.
A car travels 120 km in 2 hours. What is its average speed in km/h?
Beginner60 km/h
Average speed = total distance / total time = 120 km / 2 h = 60 km/h.
An object moves from point A to B and returns to A. What is its displacement?
BeginnerZero
Displacement is the change in position. Since the object returns to its starting point, the net change in position is zero, regardless of the distance traveled.
