the unit of distance is meter or metre (m)
the unit of time is seconds (s)
so distance/time = m/s
8.5m/1.8 seconds = 4.7
just put 4.72 because 2 is not terminating or if there are more numbers written in the answer just put two decimals on it.
Friction, caused by things in physical contact with each other, is largely absent in space. ... There is no air resistance in space because there's no air in space. 3. GRAVITY: Gravity, which will slow down a ball thrown up in the air, is present in space.
*motion - action or process being moved
*friction - resistance that one surface of object encounters when moving over another
*magnitude - refers to the size (length) or strength of the force
Let speed is equal to the distance over time.
r is the average speed
d is the distance travelled
time is the total time interval
d = 820 km
t = 27 hrs
