Intro to 1-D Motion Video

What is the primary focus of physics?

• The study of chemical reactions and elements.

• The science of how the world, and the whole universe, works.

• The analysis of biological systems and organisms.

• The exploration of historical events and human societies.

Which of the following are essential conditions used to describe an object's physical place and movement in the universe?

• Color, shape, texture, and size.

• Temperature, pressure, density, and volume.

• Time, position, velocity, and acceleration.

• Mass, weight, force, and energy.

What characterizes one-dimensional motion?

• Movement that occurs freely in all three dimensions.

• Movement that involves only changes in speed, not direction.

• Movement that can only occur back and forth along a single line.

• Movement that is always circular or rotational.
