Document Summary

Kinematics in one dimension the description of motion along a straight line. Scalar: described by a real number with units: mass, charge, energy. Vector: described by a scalar and direction in space: displacement, velocity, force: vector components and arithmetic, vectors in 3 dimensions, unit vectors, i,j,k. Kinematics in two dimensions: position, velocity, acceleration vectors. Position points from an origin to a particle. A=dv/dt: constant acceleration in 2d, free fall in 2 d. Effect of air resistance is assumed negligible. Objects follow a parabolic path: uniform circular motion. Velocity changes because direction changes: tangential and radial components of a. Radial: centripetal: due to the change in direction. Tangential: equals the rate of change of speed. Period: time required for one complete revolution: Angular velocity: =v/r: relative velocity and acceleration. Inertial frames: accelerations are always the same in all, velocities are relative to each other. Ne(cid:449)to(cid:374)"s la(cid:449)s of (cid:373)otio(cid:374: ne(cid:449)to(cid:374)"s la(cid:449)s.
