Motion On an Incline
In this experiment, you will study the motion of an object moving without friction down an
incline. In particular you will answer the following questions.
1. What is the motion of the object?
2. How does
Logger Pro Tutorial
Logger Pro is the software program we will be using to collect data this quarter. There are a number of
quick items that will help you use the program efficiently. This tutorial focuses on how to use the tools

Spring Forces and Interacting Forces
The objectives of this lab are to explore the force exerted by a spring or a group of springs, and
to explore the forces between interacting objects. You will answer the following question
The objective of this lab is to explore collisions of objects on frictionless surfaces. You will
answer the following questions.
1. What happens to the momentum and the kinetic energy of an object that bounces el
This sheet is to help you learn an analysis technique you will need to complete some lab reports.
In many of the labs we will find that the dependent property depends on two or more variables.
For example, lets say that property z

Momentum and Impulse
Linear momentum is defined as the
mass of an object multiplied by its
p = mv
Just like forces and other vectors,
momentum can be split into
The unit of momentum is kg*m/s
Work and Energy
Energy is the ability to do work.
Energy is not able to be seen or
touched, but its effects are visible.
Something has energy if it hurts
when it touches you.
Energy is measured in units of Joules.
1 Joule = 1 N*m
