Velocity Flashcards
What is velocity?
Velocity is the distance travelled per unit time in a specified direction. Velocity is also defined as the rate of change of displacement.
What is the formula for velocity?
Displacement/ Time Taken
When an object moves in a straight line, the ______ of the displacement is equal to the distance ________. However, displacement involves _______ while distance does not. They are not het same.
Magnitude
Travelled
Direction
There may be a situation in which the ______ of an object’s velocity is equal to the object’s speed. Nevertheless, velocity and speed are still different. Velocity involves _______ while speed doesn’t.
Magnitude
Direction
In many cases objects do not move at a _____ (the same) velocity for the entire motion being investigated. In such cases the _____ velocity is calculated as opposed to simply “the velocity”.
Constant
Average
The magnitude of the average velocity is often quite different in size to the average ____. However, the instantaneous speed and velocity of a moving object are always ____ in size.
Speed
Equal
