Forces: Free-body Diagrams

Question 1

Define “free-body diagrams”.

Answer 1

Diagrams used to show size and direction of all forces acting upon an object in a situation
Object is represented as a dot
Forces are represented as arrows
Length of arrow is the magnitude
Direction of the arrow is the direction of the force acting on the object

Question 2

Define “balanced forces”.

Answer 2

Every force is opposed with an equal force of the same strength.

Question 3

Define “constant velocity”.

Answer 3

Balanced forces -> at rest/ moving left, right, up, down at a constant speed

Question 4

Define “unbalanced forces”.

Answer 4

One/more forces are not counteracted by an equal opposing force
When forces are unbalanced, there is a net force/resultant force.

Question 5

Define “net force”.

Answer 5

The result of adding up all the forces as vectors

The net force is a vector with a magnitude (number) and a direction
