Kinematics Flashcards
When might calculus be used instead of SUVAT?
when acceleration is not constant
What is the gradient in a displacement time graph?
velocity
What is the gradient in a velocity time graph?
acceleration
What is the area equivalent to in a v/t graph?
displacment
What is the area equivalent to in a a/t graph?
Velocity
What does SUVAT stand for?
S= displacment U= initial v V= final v A=acceleration T=time
What is the difference between velocity and speed?
velocity has direction but speed doesnt
What is the difference between displacement and distance?
Distance is the whole distance covered whereas displacement is the distance from start to end with direction
What does r stand for in kinematics
Position vector
How do you find the resultant vector
The sum of seperate velocities
Use triangle
When an object is travelling parrallel to i what does this mean
j is constant (k)
What does it mean is a particle is travelling northwest in relation to i and j
i = j
