The velocity of an object at a specific moment

• constant velocity

• instantaneous velocity

• average velocity

• relative velocity

The slope of a position time graph tells us about the ___ of the object.

• elevation of the path

• velocity

• acceleration

• position

The instantaneous velocity can be found on a position time graph by finding the

• slope of the tangent line at that moment

• area under the curve

• length of the line

• average velocity

The slope of a velocity time graph tells us about the ___ of the object.

• elevation of the path

• velocity

• acceleration

• position

On a velocity time graph a curved line represents

• changing acceleration

• an object that is turning

• constant velocity

• constant acceleration

Select the definition of acceleration:

• Change in position over time

• Change in velocity over time

• Change in velocity per square second over time

• Change in displacement over time
