Section 1-5: Units, Standards and the SI System
Section 1-6: Converting UnitsSection 1-7: Order of Magnitude
Ch.2 Section 2-1: Reference Frames and DisplacementDisplacement is the change in position of an object, which is how far the object is from the starting point. Displacement is a quantity that has both magnitude and direction. Such quantities are called VECTORS.
Section 2-2: Average VelocityAvg. Velocity is the displacement traveled along an object’s path divided by the time it takes to travel this distance.
Velocity is used to signify both the magnitude of how fast an object is moving and the direction in which it is moving. Velocity is therefore a VECTOR.
Average velocity is defined in terms of displacement, rather than the total distance traveled.
Section 2-3: Instantaneous VelocityInstantaneous velocity is the velocity at any instant of time. More precisely, the instantaneous velocity at any moment is defined as the average velocity over an infinitesimally short time interval.
Section 2-4: AccelerationAvg. acceleration is defined as the change in velocity divided by the time taken to make this change.
Instantaneous acceleration is a very small change in velocity during a very short time interval.

Ch.3 Section 3-1: VECTORS and ScalarsA vector has both magnitude and direction, such as, displacement and force.
A scalar is described by many quantities such as mass, time, and temperature, having no direction associated with them.

Tail-to-Tip Method
Parallelogram Method Section 3-3: Subtraction of Vectors, and Multiplication of a Vector by Scalar Section 3-4: Adding Vectors by ComponentsMust know the right triangle and the trigonometric functions used to describe it (sine, cosine, tangent).
Section 3-5: Projectile Motion
Horizontal and Vertical motion are analyzed separately.
An object projected horizontally will reach the ground in the same time as an object dropped vertically.
Section 3-6: Solving Problems Involving Projectile Motion
The four constant acceleration equations from page 28 are now considered in the horizontal and vertical directions separately…PAGE 60.Section 3-7: Projectile Motion Is Parabolic
Section 3-8: Relative Velocity
Section 4-1: Force
Force is any kind of push or pull on an object
Section 4.2:1st Law - Every body continues in its state of rest or of uniform speed in a straight line unless acted on by a nonzero net force.
Law of inertia
Inertial reference frames
Section 4.3: MassMass is the measure of the inertia of a body.
Mass vs. Weight
Section 4-4:
2nd Law – The acceleration of an object is directly proportional to the net force acting on it and is inversely proportional to its mass. The direction of the acceleration is in the direction of the net force acting on the object. (SF = ma)
Section 4-5:3rd Law – Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
For each force be clear on which object it acts, and by which object it is exerted. SF = ma applies only to forces acting on a body.
Section 4-6: Weight—the Force of Gravity; and the
The magnitude of the force of gravity on an object is commonly referred to as the weight of the object.
Contact Force
Normal Force – A contact force that acts perpendicular to the common surface of contact.
Section 4-7: Solving Problems withNet force – the vector sum of all forces acting on an object
