Today we are doing an example of dropping or throwing objects into the air and doing calculations related to this knowing that the acceleration of gravity (for all objects regardless of mass) is 9.8 m/s/s. We will then perform a quick investigation to determine the height of an immeasurable height within the school using this technique.
Kinematics Equations - Development
Today we are working on developing the 5 kinematics equations on your own. Tomorrow we will write out these five equations and also use them to solve problems.
Today we will do some example problems of simple projectile motion (objects falling or being thrown vertically). We will also start the 15 question kinematics problems assignment. This comes in three parts. Part A are the basic types, Part B involve more thinking and Part C involve more complicated type problems. You are expected to solve all 15 in preparation for the upcoming evaluations.
Today we are performing a uniform acceleration investigation. You can download the investigation sheet below.
Finding accelerations and distances using equations and by analyzing graphs.
1. Today we are completing the average speed problems and uniform motion investigation.
2. Uniform Acceleration (Introduction)
Today we are learning the basics of ACCELERATION. Acceleration is simply the change in speed (velocity) over time. Things can speed up, slow down or change direction - all of these are considered acceleration. If the acceleration is constant...meaning a consistent change in an objects speed, then the acceleration is considered uniform.
Uniform Motion Investigation
What is uniform motion and how is it represented on a speed-time graph? What does the solve of a distance-time graph represent?
In this section we will be solving some basic problems related to average speed, distance and time. We will also review the basics of experimental skills (dependent, independent, and control variables) and we will be doing a uniform motion investigation with dynamics carts.Tutorials
Average Speed Calculation
The following assignment sheet is used to practice solving average speed problems.
