Physics and Measurement
Measurements Basic units of measure LengthMeter MassKilogram (1kg = 2.2lbs) WeightNewton (1kg = 10N) TimeSecond
Scalar vs. Vector Scalar Measurement that has magnitude (number) 5m Vector Measurement that has magnitude and direction 5m, east
Scalar vs. Vector Distance Measurement of length Displacement Measurement of distance in a certain direction Vector measured from starting point directly to end point
Distance vs. Displacement A person walks 2 miles North, then 4 miles East, and finally 2 miles South. Distance = 8 miles Displacement = 4 miles, East
Scalar vs. Vector Speed Amount of distance traveled in a given amount of time (m/s) Velocity Speed in a direction
Vectors ForForce (weight) EverElectric Field Strength AtAcceleration The Torque DDisplacement MMomentum VVelocity
Vector Components Vectors can be broken down into horizontal and vertical components Right Triangles θ H Hcos θ Hsin θ
Examples Find horizontal and vertical components 20m 30° X Y X = Hcos θ Y = Hsin θ X = 20cos 30 Y = 20sin 30 X = 17.32m Y = 10m
Examples Find horizontal and vertical components 4.6m 60° X Y X = Hcos θ Y = Hsin θ X = 4.6cos 60 Y = 4.6sin 60 X = 2.3m Y = 3.98m
Direction Vectors always have a direction N E S W
Direction What if you dont know which way is north? 90° 0° 270° 180°
Standard Convention 90° 0° 270° 180°
Example A student walks 6m at 0° and then 8m at 90°. What is the resultant displacement? 6m 8m R R= 10m, 53° θ
Unit 4 – Lecture 3. Distance Distance – the length traveled by an object Practice – What is the distance? Pattie walks 4 km North, then 3 km East Joe.
Vectors A vector is basically an arrow that represents the magnitude and direction of a measurement. The length of the vector represents its magnitude.
Where and When?! Ch. 3 Section 2. Coordinate Systems Tells you where the zero point of the variable is located and the direction in which the values measured.

Solving 2-D Vectors Graphically Physics. Why? O You can and people have accurately represented a situation by drawing vectors to scale in order to recreate.
Movement Aim: How can we distinguish between speed, velocity and acceleration?
Section Many of the quantities you work with in mathematics, such as those representing area, volume, and money in a bank account, are measures,
An object that is moving in two directions The directions are horizontal and vertical Also called X and Y on a graph Has a single force that acts upon.
What is a vector?. 1. What is the direction of this vector? 30 Degrees.
Vectors & Scalars Vectors are measurements which have both magnitude (size) and a directional component. Scalars are measurements which have only magnitude.

Objectives After completion, you should 1. Know the term displacement, velocity,acceleration and deceleration for motion in a straight line 2. Be familiar.
Do Now Period Homework Answers 1. t = 1.10 s, vf = 10.8 m/s 2. t = 5.10 s, d = m 3. vf = 5,772 m/s 4. d = 19.6 m, vf = 19.6.
Topic 1.3 Extended B - Components of motion Up to now we have considered objects moving in one dimension. However, most objects move in more than one.
10.2 Vectors and Vector Value Functions. Quantities that we measure that have magnitude but not direction are called scalars. Quantities such as force,
