Net force =
-10 m/s/s
mass x acceleration
0 N
mass x acceleration due to gravity
Net force is the sum of all forces
True
False
The acceleration of an object is 10 m/s/s. If the NET FORCE is decreased by ONE-HALF of the original force, then the NEW ACCELERATION would be _____m/s/s.
10 m/s/s
20 m/s/s
5 m/s/s
-10 m/s/s
The acceleration of an object is 10 m/s/s. If the Mass is decreased by ONE-THIRD of the original force, then the NEW ACCELERATION would be _____m/s/s.
30 m/s/s
3.33 m/s/s
9 m/s/s
-10 m/s/s
Mass = 5 kg
Acceleration = 1 m/s/s
What is the NET FORCE
1 m/s/s
5 m/s/s
1 N
5 N
A person kicks a soccer ball. What is the ACTION FORCE?
Soccer ball pushes against the persons foot
Person's foot pushes against the soccer ball
There is not action force
Ground pushes up on the soccer ball
A person kicks a soccer ball. What is the REACTION FORCE?
Soccer ball pushes against the persons foot
Person's foot pushes against the soccer ball
There is not reaction force
Ground pushes up on the soccer ball
Force Action = Force Reaction
Why is this statement incorrect?
All forces are not equal
A Reaction force happens before an Action Force
All forces are equal but are oppositely directed
