A ball is kicked and rolls along a level field until it comes to a stop. What is most responsible for the ball coming to a stop?
friction
If a car is moving backward along a road, can its speed be measured?
Yes, because as long as a vehicle is moving forward or backwards, speed can be measured
Which statement best describes how a multicellular organism survives?
The cells have different functions, and together they are essential for the survival of the organism.
A wagon is pushed in a straight line. How would an increase in friction on the wagon wheels affect the wagon?
It would cause the wagon to move faster.
It would cause the wagon to change mass.
It would cause the wagon to change direction.
It would cause the wagon to slow down.
The wagon would slow down
Which best describes a hurricane?
a low-pressure weather system
a high-pressure weather system
a cold front
