Forces To Know + Un/balanced Forces Flashcards
What are balanced forces? What does it mean for the object it acts on?
Forces that act in opposite directions on one object. They act in the same strength/magnitude and it means the object they act on is in equilibrium.
If an object is in equilibrium, what is the resultant force acting on the object?
Resultant force = 0
What are unbalanced forces? What does it mean for the object it acts on?
When two forces acting on an object are in different directions with different strengths/magnitudes. There’s forces are unbalanced and object is not in equilibrium which means it’ll either change its speed or change its direction
What does gravity do to objects!
It gives it a weight
It makes objects fall
It attracts objects to planets/earth
What does friction do to an object!
It slows down moving objects, it stops objects from moving
What does air resistance do to an object!
It slows down moving objects in the air
What do drag forces do?
Slow down moving objects in gas or liquid
What does upthrust do to an object!
It pushes objects up in liquids or gas
What do driving forces do to an object?
Makes objects move
What do support forces do to an object!
Stops objects from falling
