When acceleration is negative, what does that mean?
150 meters
the car is slowing down or going opposite from the direction of the velocity
m/s2, m/s, s, m
no
-1 m/s2
800,000 meters
the rate of change in velocity
total displacement divided by the time interval during which the displacement occured
what are the units for acceleration, velocity, time and displacement, respectively?
150 meters
the car is slowing down or going opposite from the direction of the velocity
m/s2, m/s, s, m
no
-1 m/s2
800,000 meters
the rate of change in velocity
total displacement divided by the time interval during which the displacement occured
