Velocity is measured in
m/s
Time in physics is always measured in
Seconds
how is velocity different to speed?
it has direction
Define acceleration
Rate at which an object changes it’s velocity
define declaration
Acceleration in a direction that is opposite to the direction of motion
Define constant velocity
an object travelling with uniform motion in a straight line
Define change in velocity
change in speed or direction
a card change a velocity of 120 km/h and an acceleration of 48m/s⬆2 what is the time?
2.5 hours
a car has a change of velocity of -60 km/h for 4 hours. What is it’s acceleration?
-15 km/h⬆2
True or false?
Negative acceleration ALWAYS means an object is slowing down
False
