SP1d Velocity/time graphs

Question 1

Interpret velocity/time graphs qualitatively.

Answer 1

If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Question 2

How doesdistance travelled from the area

under a velocity/time graph

Answer 2

The distance travelled by an object can be calculated from the area under a velocity-time graph.
