2m/s2
A runner’s velocity is 3.5 m/s. Convert this to cm/s

flight path of a projectile
Trajectory
If acceleration stays the same, motion becomes predictable and follows specific patterns.
principle of Constant Acceleration
V2
Later or Final velocity
On a velocity–time graph, what does the area under the line represent?
displacement
A runner completes a sprint in 0.08 hours. How many seconds is this?
288 seconds
horizontial displacement of a projectile at landing
Range
Distance has no direction.
Displacement has both magnitude and direction.
Principle of Distance Vs Displacement
