PHYSICS PHYSICAL MEANING

v-t (velocity-time) graph shows the variation of velocity with time. The slope of which is the acceleration, and the area under which denotes the displacement.

s-t (displacement-time) graphs shows the variation of displacement with time. The slope of which at a certain time is the velocity at that time.
a-t (acceleration-time) graph shows the variation of acceleration with time.
Q: 同埋 見到physical menaing題目應該點答? 同埋要答d咩
As the name inplies, "physical meaning" is just the meaning of the term in physics.

For example, the term "work done". In physics, work will be done if a force moves through a certain displacement. If the force doesn't move, there is no work done.

This is different from the common meaning of doing work, in which holding a heavy object without any movement is also considered as a work-done.
