Force Diagram Review

An object in a force diagram should be drawn using these shapes. square or rectangle
The arrows in a force diagram should always point in this direction from the object. Away from the object.
The arrows in a force diagram are called this. Vectors
The word that describes the amount of force is called this. magnitude
In order for an object o accelerate it must have this. nonzero net force
An object sitting still or moving at a constant speed an direction is said to have this. zero net force
If a big box is sitting still on the floor and gravity is pulling it down with 200N, what is the floor doing? Pushing up with 200 N according to Newton's 3rd Law.
This is the force that is created when two objects are in contact. Friction
If the arrows of a force diagram are equal in length and on opposite sides of the object, what do you know about these forces? They are balanced.
Describe what a force diagram would look like if the forces on the object are unbalanced. The arrows would be on opposite sides of the square or rectangle and of different lengths with different forces.
What is acceleration? A change in motion... speed up, slow down..change direction
How do you know if something is not accelerating? It is not moving or moving at a constant speed.
The arrows of a force diagram should always be labeled with this. A number and the letter N for newtons.
A force diagram that is unbalanced will do this. accelerate
Describe what the net force diagram looks like for unbalanced forces. A square with only 1 arrow pointing in the direction of acceleration.
The length of the arrow in a force diagram represents this. The amount of force, longer the arrow more force, shorter the arrow, less force.
