Distance Speed and Time Quiz

Average speed is calculated as total distance divided by total time: 4 miles / 2 hours = 2 mph.

Slope is defined as the change in the vertical direction (rise) divided by the change in the horizontal direction (run).

On a distance vs time graph, a negative slope indicates that the distance from the starting point is decreasing, meaning the object is moving back toward the origin.

By convention, distance vs time graphs plot the independent variable (time) on the x-axis and the dependent variable (distance) on the y-axis.

The unit m/s stands for meters per second, which is the standard SI unit for speed or velocity.

Speed is a scalar quantity and does not indicate direction, whereas velocity is a vector quantity that includes direction. Therefore, saying speed indicates direction is false.

Instantaneous speed refers to the speed of an object at a specific, precise moment in time. It does not account for the entire duration of a trip.

Average speed is defined as the total distance traveled divided by the total time taken to cover that distance.

Distance is calculated by multiplying the speed of an object by the time it has been traveling.

Speed is defined as the rate at which an object covers distance over a period of time.
