Physics and Mass Help
Introduction The earliest physicists were curious about the way matter behaves: What happens to pieces of it when they move or are acted on by forces. Scientists set about doing experiments and then tried to develop mathematical models (theories) to ...

Physics and Force Help
Introduction to Force Imagine again that you are in a spacecraft orbiting the Earth, so everything in the cabin is weightless. Two objects float in front of you: a brick and a marble. You know that the brick is more massive than the marble. ...

Physics and Displacement Help
Introduction to Displacement Displacement is also known as distance . Unless otherwise specified, displacement is defined along a straight line. We might say that Minneapolis, Minnesota, is 100 km from Rochester, Minnesota, ...

Physics and Speed Help
Introduction to Speed Speed is an expression of the rate at which an object moves relative to some defined reference point of view. The reference frame is considered stationary , even though this is a relative term. A person ...

Velocity Help
Introduction to Velocity Velocity consists of two independent components: speed and direction . The direction can be defined in one dimension (either way along a straight line), in two dimensions (within a plane), or ...

Acceleration Help
Introduction to Acceleration Acceleration is an expression of the change in the velocity of an object. This can occur as a change in speed, a change in direction, or both. Acceleration can be defined in one dimension (along a straight ...

Scalars and Vectors Study Guide
Introduction We start this lesson by briefly considering a reference frame and the coordinates of a point-like object relative to it. Next, we make a distinction between scalar and vector quantities, and present examples of both. At the end of the chapter, we take ...
