Balanced / Unbalanced Forces Flashcards
(16 cards)
Is it balanced or unbalanced when…
- No movement occurs
Balanced
Is it balanced or unbalanced when…
- An object is moving at a continuous speed
Balanced
Is it balanced or unbalanced when…
- Inconsistent movement when a force is applied
Unbalanced
What effects could a force have on a object
-Accelerate it
- Decelerate it
- Change its shape
- Change its direction
True or false;
Gravity is the force that makes us fly off the earth
False
True or false;
Gravity is caused by mass (amount of matter)
True
Does the amount of mass determine the amount of gravity needed (more mass = more gravity)
Yes / true
What is a reaction force / support force…
The opposing force of gravity/weight
What is the force that pushes down
Gravity
Gravity/weight
What is the force that pushes up
Reaction force
Support force
What happens if both force are equal and in the different directions
balanced / unbalanced - what does this mean, add / subtract
The force is balanced, staying stationary / still
You subtract together the Newtons of each arrow to get 0N
What happens if both force are different and in the same direction
balanced / unbalanced - what does this mean, add / subtract
The force is unbalanced,
You add together the Newtons of each arrow
What happens if both force are different and in the different directions
balanced / unbalanced - what does this mean, add / subtract
The force is unbalanced,
You minus together the Newtons of each arrow
What is forces measured in
Newtons (N)
What can be calculated if the size and direction of the force is known
Resultant force
Does the vehicle move in the way of friction or push
Depends on the larger force - bigger arrow - bigger Newton
