Velocity Flashcards

All 4 cards in this deck

What is velocity?

The speed of an object in a given direction. It is a vector quantity.

True or false? An object can have a constant speed but a changing velocity.

True. If its direction changes, its velocity changes even though its speed stays the same.

Why can the average speed and the average velocity of a car between two speed cameras be different?

Velocity is a vector and includes direction; if the road is not straight the direction changes, so the velocity differs from the speed.

How do you state a velocity fully?

e.g. a train moving at 30 m/s along a track heading east

Give the speed and the direction: 30 m/s east.
