If I move 10 meters north, then turn 90 degrees and move another 10 meters, what is my distance travelled and what is my displacement (magnitude only)?
Distance = 20 m
Displacement < 20 m
Distance < 20 m
Displacement < 20 m
Distance = 20 m
Displacement > 20 m
Distance = 20 m
Displacement = 20 m

Velocity: Constant, Acceleration: Constant
Velocity: Constant, Acceleration: Changing
Velocity: Changing, Acceleration: Constant
Velocity: Changing, Acceleration: Changing

b) A 0.0100 kg bullet fired at 600.00 m/s
a)
b)
They are the same!
