Motion in one Dimension

How fast one variable changes in relation to another variable on a graph is called-

• distance

• run

• slope

• rise

The distance an object moves per unit of time represents the-

• speed

• rate

• velocity

• acceleration

Average speed is calculated by-

• Total time/Total distance

• Total speed/ Total acceleration

• Total distance/Total time

• Total velocity/Total distance

If a runner is increasing her speed, would her initial speed be more or less than her final speed?

• It would be the same

• It would be more

• It would be less

• It would depend on what speed she started at and what speed she ended at

Slope of displacement -time graph gives

• velocity

• speed

• acceleration

• displacement

In the v-t graph, a graph parallel to time axis, the the acceleration is

• negative

• positive

• zero

• both positive and negative

Calculate the distance traveled by the body between 10 to 20 seconds

• 
• 100 m

• 150 m

• 200 m

• 250 m

Distance traveled by the body in the last 20 s is

• 
• 150 m

• 200

• 250

• 300 m

Alan travels 100 km in 5hrs. Find his average speed in km/h

• 5km/hr
• 10km/hr
• 50km/hr
• 20km/hr

Final position minus the initial position is called 

• displacement
• distance
• magnitude
• time interval
