Displacement, Velocity and Acceleration as Vectors
The displacement, velocity and acceleration of a particle have the same relationship in vector form as when motion is along a straight line:
Integration and differentiation are done in a natural way, with the direction vectorsand being constant vectors.
The position vector,of a particle at timeis given by
Find expressions for the acceleration and velocity of the particle.
The acceleration vector,of a particle at timeis given by
Find expressions for the velocityand accelerationof the particle, ifandat
