Kinematics·v = u + at
u — Initial velocity5.0 m/s
a — Acceleration3.0 m/s²
t — Time4.0 s
Final velocity v
17.00m/s
v = 5.0 + 3.0 × 4.0 = 17.00
Velocity scale
17.0 m/s
03060 m/s
Displacement
44.0 m
s = ut + ½at² = 5.0×4.0 + ½×3.0×4.0²
Physics insight
Classic UAM — both u and at contribute meaningfully to final velocity.
Study tip
After playing with a formula here, go to the topic page and attempt the quiz questions. You'll find the numbers make much more intuitive sense once you've seen the variables move.
