P2.1 Flashcards
How do you calculate distance travelled (m)
Speed (m/s) x time (s)
How do you calculate average speed (m/s)?
Total distance (m) divided by total time (s)
What is a scalar
Something that only has a magnitude and not a direction.
What is a vector
Something that has both a magnitude and a direction
What is displacement
The shortest distance between 2 points
What is stationary speed on a graph?
A straight, horizontal line
What is constant speed on a graph?
A straight diagonal line
What is slowing down on a graph (decelerating)?
A curved line that goes up and then bends into a vertical line
What does a speeding up graph look like (accelerating)?
A curve that goes upwards
How do you calculate acceleration?
Change in velocity divided by time
How do you calculate speed?
Change in distance divided by time
How do you calculate velocity?
Change in displacement divided by time
How do you calculate final velocity?
V(2) = U(2) + 2as
What is U
Initial velocity
What is s
Displacement
