For National 4 Physics describe and examine the motion of a moving object, calculating acceleration, distance and average speed.

The area under a velocity-time graph gives the displacement. The velocity-time and acceleration-time graphs for common motions are shown below.

A study shows that an irreversible loss of the ice sheets, and a corresponding acceleration of sea level rise, may be imminent if global temperature cannot be stabilized below 1.8 degrees Celsius.
