Solving problems is an essential part of the understanding process.
Motion in two dimensions with one dimensional acceleration (projectile) is analyzed with component motions in coordinate system, whereas motion in two dimensions with two dimensional acceleration (circular motion) is analyzed with the help of component accelerations - tangential and normal accelerations.

A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.
Students construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket.
In this lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. Already encountering simple machines everyday, students will be alerted to their widespread uses in everyday life. This lesson serves as the starting point for the Simple Machines Unit.
Without highly controlled jet propulsion, rockets and other aircraft would zip through the air as unpredictably as so many untied party balloons. In this video segment adapted from ZOOM, two cast members find out how slowing the amount of air expelled from a balloon and changing the direction of that air can affect the balloon's behavior. Grades 3-8
Air pressure is pushing on us all the time although we do not usually notice it. This activity will discuss the units of pressure and give the students a sense of just how much air pressure is pushing on them.
Analysis of resultant motion is best fit to the principle of independence of motion in mutually perpendicular directions.
Analyzing collision situation involves application of basic conservation principles in a closed system.
The angular momentum in rotation is a subset of angular momentum about a point in general motion.
Objective questions, contained in this module with hidden solutions, help improve understanding of the topics covered under the module "Angular momentum".
Angular quantities are not limited to rotation about fixed axis only.
Students will design and build a prototype of an artificial limb using a simple syringe system as an introduction to bioengineering. Students will determine which substance water (liquid) or air (gas) will make the appendage more efficient.
Artificial satellites are the backbone of modern communication systems.
Students learn how forces are used in the creation of art. They come to understand that it is not just bridge and airplane designers who are concerned about how forces interact with objects, but artists as well. As "paper engineers," students create their own mobiles and pop-up books, and identify and use the forces (air currents, gravity, hand movement) acting upon them.
The ASPIRE Lab is now one of the most innovative and interactive science education websites available on the Internet. You will find not only fun interactive labs, but well designed and produced curriculum content, created by teachers for teachers. The powerful combination of inquiry-based content, along with interactive, hands-on labs provides a powerful visualization tool for you and your students to use. Best of all, the ASPIRE Lab is free!

This activity is a hands-on investigation that teaches students that air resitance affects how things move and that pressure from compressed air can move things.
Rockets need a lot of thrust to get into space. In this lesson, students learn how rocket thrust is generated with propellant. The two types of propellants are discussed and relation to their use on rockets is investigated. Students learn why engineers need to know the different properties of propellants.
