A
True or false: The more force you apply to an object, the faster it will move?
True
True or false: Increasing the mass of an object makes it harder to change its motion?
True
True or false: Smooth surfaces create more friction than rough surfaces?
False
Definition: The action or process of moving or being moved?

Definition: the amount of matter or substance that makes up an object?
Mass
Definition: A push or a pull on an object?
Force
Definition: name the four main directions.
North, East, South, West

b) Gravity
c) Air resistance
d) Magnetism
b) gravity
Multiple choice: What happens to an object when the force applied to it increases?
a) It slows down.
b) It stays still.
c) It moves faster.
d) It becomes lighter.
c) It moves faster
Multiple choice: Which of the following surfaces would create the most friction for a moving object?

d) Metal slide
c) Gravel road
Application question: Mr. Graves is pushing a toy car with the same force on a smooth tile floor and a carpeted floor. On which surface will the car travel farther, and why?
The car will travel farther on the smooth tile floor because there is less friction compared to the carpeted floor.
Application question: If Khylee pushes a box and it starts moving and Oliver stands on the box, how will this change the box's motion? Why?
The box will move slower or may stop because the increased mass requires more force to maintain the same motion.
Application question: Savanna kicks a soccer ball on a flat field. What two forces will eventually cause it to stop?
Gravity pulls the ball down to the ground, and friction between the ball and the ground slows it down until it stops.
