Vector Quanities Flashcards
A vector quality has
Both a magnitude and a direction
A scalar quality was
ONLY a magnitude (no direction)
When there is a positive postive and positive acceleration; what is happening to your speed
Increasing
When there is a positive direction and negative acceleration; what is happening to your speed
Decreasing
When there is a negative direction and positive acceleration; what is happening to your speed
Increasing
When there is a negative direction and negative acceleration; what is happening to your speed.
Increasing
Values at a specific time point is known as
Instantaneous velocity/ acceleration
When on a graph a positive slope represents a
Positive velocity
When on a graph a negative slope represents a
Negative velocity
When on a graph no slope represents
Zero velocity
When on a graph the steepness of a slope represents
The magnitude ( greater the steepness higer the magnitude and vise-versa)
