What is motion?
It occurs when an object changes position relative to a reference point
200
What is Newton's 2nd Law?
The greater the force, the greater the acceleration. The greater the mass, the greater
300
What are physical properties?
Properties that are observable, measurable, and will keep the same composition.
300
What is a mixture?
Two or more materials mixed and are easily separated.

What is speed and its formula for average speed?
The distance an object travels per unit/time rate of change in position. The formula is distance divided by time.
