How do you find the distance from a velocity time graph?

Distance= area below the line

A train moves at a constant velocity of 50 km/h. How far will it move in 0.5 h?

25 km

An object moves at a constant speed of 6m/s. This means that the object:

Moves 6 meters every second

Using the same information from the question previous to this one, what is the travel distance of the person from the initial point in two days?

13 km

A toy car moves 8 m in 4 s at a constant velocity. What is the car's velocity?

2 m/s

A boat can move at a constant velocity of 8 km/h in still water. How long will it take for the boat to move 24 km?

3 h

Starting from the origin a car drives for kilometers east and then 7 km west. What is the net displacement of the car from the initial point?

3 km west

Starting from the origin, a person walks 6 km east during the first day, and 3 km east the next day. What is the net displacement of the person from the initial point in two days?

9 km east

A bicyclist moves at a constant speed of 4 m/s. How long will it take for the bicyclist to move 36 m?

9 s

How do you find velocity from a position time graph?

Slope=velocity

Three cars start at the same time, at the same place and move along a straight track. As they approach the finish line which car has the lowest average speed?

The car furthest from the finish line

What is the velocity of a velocity time graph with a straight horizontal line?

The velocity is constant

What is true about the velocity of a position time graph with a straight slanted line (/)

The velocity is constant

Name scalar quanitites

Time, speed, distance

Name vector quantities
