Final velocity - Initial velocity
Initial velocity + Acceleration × Time
What does instantaneous velocity represent?
Velocity over a long distance
Average velocity over a time interval
Velocity with respect to acceleration
Velocity at a specific moment in time
How is acceleration defined?
Change in speed over distance
Change in direction of motion
Change in position over time
Change in velocity over time
What is the SI unit of acceleration?
km/h
m/s²
m/s
m/s³
Which kinematic equation relates final velocity, initial velocity, acceleration, and time?
x = x₀ + vt
v² = v₀² + 2ax
x = v₀t + ½at²
v = v₀ + at
