UNIT 5: FORCES AND MOVEMENT IN THE PHYSICAL WORLD

Motion

• Force can cause a change in an object

• Motion is the change in direction, shape or position

• Forces change the position of objects

• Position describes where the object is in relation to another object

• The other object acts as a reference point.

• The reference point is used to support a change in position

Speed and Velocity

• Speed = Distance/Time

• When you divide the total distance of a trip by time you get the average speed

• Distance and displacement are not the same

• Instantaneous Speed is the actual speed at a given moment.

Forces

• A force is a push or pull, or an action that has the ability to change motion.

UNIT 6: THE UNIVERSE AND ITS ORIGIN

outer spiral arm of the Milky Way
galaxy.

Galaxies

Different types of galaxies

Galaxies are categorized by their

oval or round shape and consist
mostly of older stars.

odd shape and consist of both
older and younger stars.

• A theory that states that the universe is slowly coming back to a center.

• A theory that states that the universe started in a small mass and then expanded, the expansion cooled down the temperature and that resulted in the formation of matter, energy, space and time.
