Ib Physics Vector Presentation Figure 1.3.4 trigonometric method of solving adjacent vectors. scalar multiplication. we can also multiply (and divide) vectors by scalars. when doing so we follow a set of rules: multiplying by 1 does not change a vector 1 v = v. multiplying by 0 gives the null vector 0 v = 0. multiplying by 1 gives the additive inverse 1 v = v. Vector a quantity that has magnitude and direction. scalar a quantity that has only magnitude, and not direction. vector – a quantity that has magnitude and direction. scalar – a quantity that has magnitude but not direction. multiplying a scalar value and a vector. multiplying a vector by a scalar can change both the direction and magnitude.
Ib Physics Vector Presentation 4. the components of a vector are given as sx = 17.0 m and sy = 8.0 m. determine the resultant vector. s graphically and analytically. [s = 19 m at 25°] 5. the components of a vector are given as vx = 5.0 ms 1 and vy = 20.0 ms 1. determine the resultant vector v graphically and analytically. [v = 21 ms 1 at 76° above the –x axis]. Topic 2 mechanics. this slideshow covers topic 2 from the ib physics course, including: distance, speed and time, acceleration, distance vs displacement, speed vs velocity, vector and scalar quantities, distance time graphs, velocity time graphs, equations of motion for uniformly accelerating objects (suvat equations), resolving vectors, vertical projection, projectile motion, terminal. Vector addition and subtraction can be done by the parallelogram method or the head to tail method. vectors that form a closed polygon (cycle) add up to zero. when resolving vectors in two directions, vectors can be resolved into a pair of perpendicular components.

Acceleration due to gravity of any free falling object is given by g=9.81m s^2. this value does not depend on the mass of the object. take note that acceleration is a vector and thus has a direction. if we assume the upwards direction to be positive, the acceleration due to gravity would have a negative value of g= 9.81m s^2.
