# Kinematic equations

### The easy part: Every moving object follows simple rules, each of which can be expressed with 9th grade algebra!

Motion of an object with constant velocity http://www.f-lohmueller.de/pov_tut/animate/anim260e.htm

Motion of an object that starts with a velocity, and then accelerates http://www.f-lohmueller.de/pov_tut/animate/anim260e.htm

# How do we solve kinematics problems? ## How do we write our answers?

### Is kinematics sometimes hard? Sure, but remember this: ## Learning standards

2016 Massachusetts Science and Technology/Engineering Standards

HS-PS2-1. Analyze data to support the claim that Newton’s second law of motion is a mathematical model describing change in motion (the acceleration) of objects when acted on by a net force.

HS-PS2-10(MA). Use free-body force diagrams, algebraic expressions, and Newton’s laws of motion to predict changes to velocity and acceleration for an object moving in one dimension in various situations.

A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012)
PS2.A Forces and motion. How can one predict an object’s continued motion, changes in motion, or stability?

Massachusetts Science and Technology/Engineering Curriculum Framework (2006)
Introductory Physics. Motion and Forces. Central Concept: Newton’s laws of motion and gravitation describe and predict the motion of most objects.

1.1 Compare and contrast vector quantities (e.g., displacement, velocity, acceleration force, linear momentum) and scalar quantities (e.g., distance, speed, energy, mass, work)

1.2 Distinguish between displacement, distance, velocity, speed, and acceleration. Solve problems involving displacement, distance, velocity, speed, and constant acceleration.

1.3 Create and interpret graphs of 1-dimensional motion, such as position vs. time, distance vs. time, speed vs. time, velocity vs. time, and acceleration vs. time where acceleration is constant.
