Forces Flashcards
Newton’s third law states that every_______ has an equal and_______________
action, opposite reaction
When you hold an apple over your head how many force pairs are acting on it
1 Apple to hand
Mickey Mouse is kicked, what is the interaction pair
Action: Foot pushes face
Reaction: Face pushes foot
Result: Mickey mouse is pushed back and kicked
True or False:
Friction and Gravity are both forces
TRUE
A push or pull
Force
Which law states that when I push a book the book pushes back
Newton’s third law
Strength or Degree
Magnitude
A contact force that two surfaces exert on one other when the rub or push against each other
Friction
A non-contact force that pulls objects towards each other
Gravity
An applied force that is perpendicular to the object
Normal force
A force that is exerted on an object
Applied force
Forces acting on an object that move in opposite directions are equal
Balanced Forces
If the forces acting on the object are balanced, what are the two ways the object moves
- No Movement
- Constant Speed
Forces acting on an object that move in opposite directions or the same directions are NOT equal
Unbalanced
If the forces acting on the object are unbalanced, the object will undergo a change in ____________________ (3)
Speed, direction, position
Balanced or Unbalanced: Slowing down
Unbalanced
Balanced or Unbalanced: Constant speed
Balanced
Balanced or Unbalanced: Net Force is greater than 0
Unbalanced
Calculate the net force:
10N–>[]<–12N
2N to the left
Calculate the net force:
347982N–>[]<–347982N
0N (It would not move)
