Force Diagram Review
| Question | Answer |
|---|---|
| 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. |
