Question

what is velocity-time graph ? write the use of velocity time graph.

Answer 1

Answer:

Using data from the graph, we can calculate any acceleration , the change in speed and the change in time. We can also use graphs to calculate distance travelled. The area under a speed-time graph represents the distance travelled. This is a velocity time graph of an object moving in a straight line due North.

Explanation:

A velocity-time graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.

Answer 2

Answer:

Speed-time graphs are very useful when describing the movement of an object. We can use them to determine whether or not the object is moving at any point in time. We can also use them to see what speed the object is travelling at that point in time. Using data from the graph, we can calculate any acceleration, the change in speed and the change in time. We can also use graphs to calculate distance travelled. The area under a speed-time graph represents the distance travelled. This is a velocity time graph of an object moving in a straight line due North. Uniform acceleration 0-9, constant velocity, uniform acceleration 9-5, constant acceleration, constant acceleration 5-0
