Forces and Motion unit review

What is motion?

• When an object remains in the same position over time

• When an object changes position in relation to a reference point over time

• When an object is at rest and not moving

• When an object is visible to the human eye

What is speed?

• The time it takes for an object to move a certain distance

• The rate at which an object moves

• The total distance traveled by an object

• The formula used to calculate force
