Vectors 2-Dimensional Motion

1. Vectors &2-Dimensional Motion

2. Vectors & 2-D Motion Adding vectors graphically Vector Components Adding vectors numerically Relative velocity problems Projectiles

3. Welcome to VectorLand all you Scalarians! Adding vectors graphically Head to tail addition with ruler & protractor. Vector Components Use trigonometry. Adding vectors Numerically Resolve all vectors into components using trig’. Relative velocity problems Boats relative to water…planes relative to air, etc. Projectiles Kinematics in 2-dimensions: constant horizontal velocity, constant vertical acceleration

4. Lots of in-class practice doing trigonometry Master right-triangle trigonometry SOH – CAH - TOA Pythagorean theorem: a2 + b2 = c2 Remember “head-to-tail” addition of vectors Vector components add head-to-tail giving the original vector. Please see Mr. Jones for outside help if you are struggling with trigonometry.

5. There are two kinds of quantities… Vectors are quantities that have both magnitude and direction, such as position & displacement velocity acceleration Scalars are quantities that have magnitude only, such as distance speed time mass

6. Notating vectors: This is how you notate a vector… This is how you draw a vector…
