Position and Motion (Chapter 1 Lesson 1)

Position and Motion (Chapter 1 Lesson 1)

Author: Jason Fritz

I can answer the following questions:
•How does the description of an object’s position depend on a reference point?
•How can you describe the position of an object in two dimensions?
•What is the difference between distance and displacement?

•A reference point, a reference direction, and distance are needed to describe the position of an object.

•An object is in motion if its position changes relative to a reference point.

•The distance an object moves and the object’s displacement are not always the same.

Distance and Displacement

Distance is a measurement of length between two points. Displacement is a overall change in position of an object. Distance does not include a direction whereas displacement does include a direction.

Different Between Distance and Displacement

Distance: It is a measure of the interval between two locations. Distance is a scalar measure of the interval between two locations measured along the actual path connecting them.

Displacement: It is a vector measure of the interval between two locations measured along the shortest path connecting them.

Difference Between Distance and Displacement

There are two ways to answer this question. On the one hand, there's the sum of the smaller motions that I made: two meters east, two meters south, two meters west; resulting in a total walk of six meters. On the other hand, the end point of my walk is two meters to the south of my starting point. So which answer is correct? Well, both. The question is ambiguous and depends on whether the questioner meant to ask for the distance or displacement.

Distance is a actual path traversed by the body respective of its direction taken where as displacement gives shortest distance between two points specifying the short length direction.

The Difference Between Distance and Displacement

The change in the position of an object is not only the change in the distance, but also the change in the displacement from its initial position.

Science Battle Ship

You will use the template to draw your ships on the bottom part of the grid. On the top part will be your targets. Use the reference points (A, B, and C) and guess where your opponents ships are. The person to sink their opponent's ships first wins.

Bill Nye: Motion

Bill Nye the Science Guy explains that nothing can move or stop by itself, that everything needs a push or pull--a force--to make it move or stop. Sometimes an object might seem to be at rest, even when it is in motion. Confused? It's all relative. Relative motion, that is. This live-action, fast-paced program also features comedy, music videos, interviews with real scientists, and hands-on experiments to make the concepts presented understandable and fun.

Work, Force, Energy, and Motion

This program explains the scientific concepts of work and energy. Work is defined as the application of a force to move an object. Energy is defined as the capacity to do work. Energy may be potential or kinetic. The measure of both work and energy is the Newton-meter, or joule, which is approximately the amount of work done lifting an apple from the ground to your waist. The program gives calculated examples of work, gravitational potential energy and kinetic energy.

How Global Positioning System Works

This program explains how the Global Position System (GPS) works. A GPS receiver locates signals from four orbiting satellites and uses the information to calculate a position. The GPS system can be used to track speed and direction, the orientation of aircraft, and evidence of earthquakes or geological activity. Part of the Launch Pad series.
