What does a negative value for acceleration tell you about an object’s motion?
The object is slowing down.

What is Newton's 1st Law of Motion?
An object at rest remains at rest and an object in motion maintains its velocity unless it experiences a net force.
200
The force that attracts a body toward the center of the earth, or toward any other physical body having mass.
Gravity

What is the formula for velocity?
V = D/T

What does a positive value for acceleration tell you about an object’s motion?
The object is speeding up.

What is an example of an unbalanced force?
Answers may vary.
200
What is Newton's 1st Law of Motion?
The unbalanced force acting on an object equals the object’s mass times its acceleration.

Direction

What is an example of a projectile?
Throwing a baseball, the orbit of a space shuttle around earth, or shooting an arrow.
300
What can cause an object to accerlate?
An object accelerates if its speed, direction, or both change.
300
What is the difference between a balanced and an unbalanced force?
A balanced force does not cause a change in motion of the object, but an unbalanced force does. or A balanced force is when all the forces acting on an object are equal, while an unbalanced force is when 2 opposite forces acting on the same object are unequal.

Using what you know about Newton's Second Law, explain why a vehicle with a large mass might use more fuel than a car with a smaller mass. Assume both cars drive the same distance in the same amount of time.
According to Newton’s Second law, the acceleration of an object is inversely proportional to an object’s mass. This means that the larger the mass of an object, the greater amount of force (fuel) is required to accelerate the vehicle over a given amount of time and distance.
