Which measurement is SCALAR?
Displacement
Speed
Velocity
Acceleration
A man runs 400 m around the track ONCE. If he starts and ends up at the starting line, determine his distance and displacement.
Distance = 0 m, Displacement = 0 m
Distance = 400 m, Displacement = 0 m
Distance = 0 m, Displacement = 400 m
Distance = 400 m, Displacement = 400 m
