Question 19
19.
What happens if the force is not 0N?
Which statement is true?
objects with unbalanced forces stay still
objects with unbalanced forces accelerate or decelerate
Objects withunbalanced forces accelerate, decelerate or can be stretchedd or compressed
To calculate resultant force:
Subtract forces acting in the same direction
Add forces acting in opposite directions
Add forces acting in the same direction
A resultant force is…
A single force that has the same effect as all forces acting in the same direction
A single force that has the same effect as all the original forces acting together.
A free-body diagram
Which statement is true?
The forces on this object are balanced
The forces on this object are unbalanced
The resultantforce is 0N
Which statement is true
This object would stay still
This object would decelerate
This object would accelerate the right
