The data table describes the motion of a car over a three minute period. Which statement regarding the car's motion is true?
Minute Speed m/s Direction
1 10 North
2 12 North
3 14 North
Velocity is related to speed, but it must include the direction that an object is traveling.
Velocity is the speed an object is traveling plus the direction the object is traveling.
5 m/s north is an example of velocity.
5 m/s is not velocity, it is speed. This is because there is no direction added to the speed.
If the speed of a moving object changes, its velocity also changes.
Velocity can change while speed remains unchanged. A change in direction at constant speed is a change in velocity, but not a change in speed.
Is this a change in velocity?
A car is going south on a highway at 70 kilometers per hour. The car turns east and continues to travel 70 kilometers per hour.
Is this a change in speed?
A car is going south on a highway at 70 kilometers per hour. The car turns east and continues to travel 70 kilometers per hour.
This is a change in velocity because the car changes direction.
This is not a change in speed because the car remains at a constant speed of 70 km/hr.
