Vectors Flashcards
To find the scalar quantity of a vector…
you find the magnitude of the vector √ i^2 + j^2
Difference between scalar and vector
A vector has both magnitude and direction
Velocity
Rate of change of displacement
On a displacement-time graph the gradient represents…
Velocity
If the displacement-time graph is a straight line then…
Velocity is constant
Average Velocity =
displacement from starting point / time taken
Average Speed =
total distance travelled / time taken
Acceleration
Rate of change of velocity
In a velocity-time graph the gradient represents…
Acceleration
If the velocity-time graph is a straight line then…
Acceleration is constant
The area between the velocity-time graph and the horizontal axis represents
Distance travelled
What does SUVAT stand for
S = displacement U = initial velocity V = final velocity A = acceleration T = time
To find the resultant force you must
add vectors together
