What causes acceleration?
Mass and acceleration are Inversely Proportional to each other. What does this mean?
Acceleration and Forces are Directly Proportional to each other. What does this mean?
What is the direction of friction in relation to a moving object?
What is the acceleration of an object at terminal velocity?
What is the difference between weight and mass?
What is the equation for Force?
What is the equation for Δx when acceleration is present?
When dealing with forces, what is the equation for acceleration?
When an object is at free fall and weighs 1N, what is it net force?
When an object is at rest, what is the net force applied to the object?
The combination of all forces on an object is called the ……
If the Force applied to an object is equal to the Friction, will an object have an acceleration?
Could the object be at rest? Could the object be in motion?
What net force does a sliding crate experience when you exert a force of 110 N and friction
between the crate and the floor is 100N?
How is inertia affected by weight and mass?
What is the relationship between acceleration and gravity?
What happens to acceleration when air Resistance (R) is equal to mass x gravity (mg)? What
happens when mg is greater then R?

Unbalanced Force
When mass increases Force and acceleration decreases
When Force increases acceleration increases
Always opposite of the motion
0 m/s2
Mass of an object is constant and Weight is dependent on gravity. No gravity = no weight
Force = Mass x Acceleration
Delta x = 1/2at2
Acceleration = Force/Mass
1N Gravity = Force
0N
Net force
Acceleration = 0, Yes the object could be at rest, Yes the object could be moving at a constant
acceleration
14. 10N
15. The greater the mass = the greater the inertia Weight has no affect on inertia
16. In a free fall situation they are the same
17. When mg is greater than R, acceleration increases, when R = mg, acceleration reaches zero and
the object is at terminal velocity
18. The acceleration of an object is directly proportional to the net force acting on the object, is in
the direction of the net force, and is inversely proportional to the mass of the object
