Answer:
Speed is solved with time and distance but has no direction
Average velocity is solved with Δx/Δt and has a direction

The number of pulse beats elapsed before the rubber ball hits the ground can be obtained when you carry out the experiment yourself. However, the pulse beat method of timing used by Galileo is not reliable because it varies from time to time.
Galileo was interested in studying how objects fall. His discovery was that all objects had the same acceleration irrespective of their mass. This observation was in direct contrast to Aristotle's assertion that the velocity of objects is proportional to their mass.
However, he used his pulse beats as timer during the experiment. This method is unreliable because the pulse beats of a person changes depending on the person's state of mind. A stop clock could have been a more reliable timer than pulse beats.

Hello!
A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?
We have the following data:
m (mass) = 1350 kg
v (velocity) = 12 m/s
KE (kinetic Energy) = ? (in Joule)
Formula to calculate kinetic energy:
Solving:
_______________________
It depends upon the type of graph that you are talking about,
If the graph is Velocity - Time graph, then time lies on the X axis and speed on the Y axis.
If it is Distance - Time graph, the time lies on the X axis and distance on the Y axis.
But generally, it is ALWAYS TIME IN THE ‘X’ AXIS AND DISTANCE ON THE ‘Y’ AXIS.
