2.4.11 Vectors and Scalars
Lesson Overview:
Scalars are units with only a quantity/magnitude such as speed, mass, and time. Vectors are units with both magnitude AND direction such as velocity, acceleration, and force. Always use SI Units:

2.4.12 Velocity and Acceleration
1.4.13 Graphs of Motions
Lesson Overview:
Use and interpret displacement vs time and acceleration vs time graphs to describe linear motion. Textbook pages: 131-133
This is the running man app that can be used to help describe graphs of motion.

2.4.14 Equations of Motion
Lesson Objective:
There are five possible variables used in problems of linear (1 dimensional) motion. Knowing any three of them, you can solve for a fourth unknown by using the Kinematic Equations You should become VERY comfortable with the Equations for Motion

2.4.15 Motion under Gravity
Lesson Objective:
Use the kinematic equations to solve problems where gravity is involved. These problems involve vertical motion. Acceleration due to gravity:

2.4.16 Vectors and 1D Relative Motion
Lesson Objective:
Vectors can be added or subtracted to solve problems where one objects moves relative to another observer, object, or medium. This section is mostly concerned with the math involved with vectors. The next section is involved with relative motion. Textbook pages: 136-138 |
These first four videos cover the math of adding and subtracting vector quantities
Note: the first two videos in this section are from the perspective of a physics teacher. The second two are from the perspective of a math teacher. Both have valid methods, see if one works better for you. |
These videos are the first four in a series about using vectors to describe relative motion.

2.4.17 Vector components and 2D Relative velocity
Lesson Overview:
The motion of objects moving at an angle can be broken into their horizontal and vertical components. The horizontal and vertical components can be used to make calculations for relative motion problems. Textbook pages: 139-141 |

2.4.18 PROJECTILE MOTION
Lesson Objective
This topic combines every aspect of motion covered so far in this chapter. Projectile motion is motion in two dimensions. Simple uniform motion in the horizontal direction will be combined with linear motion in a vertical direction (usually with gravity as acceleration). Vector components of the initial and/or final trajectory are often involved Textbook pages: 144-148 |
The following videos help explain how to solve problems with projectile motion.
