What Is a Speed Graph

A speed – time graph shows us how the speed of a moving object changes with time. • The steeper the graph, the greater the acceleration. • A horizontal line means the object is moving at a constant speed.

What's a speed graph?

Speed-time graphs A horizontal line on a speed-time graph represents a steady speed. This can also be called a constant or uniform speed. A sloping line on a speed-time graph represents an acceleration . The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down.

Is velocity a speed?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. … For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.
