Friction & Weight
High School Physics
| Question | Answer |
|---|---|
| Friction acts in this direction | Opposite from the velocity |
| mass | amount of matter |
| weight | gravitational force |
| mass unit | kg |
| weight and friction unit | N |
| friction and weight sign | negative |
| mass is a scalar | true |
| weight is a scalar | false |
| if the object moves to the left, friction is to the | right |
| weight acts in this direction | down |
| If an object is falling, friction is in this direction. | up |
| Your weight in space | zero N |
| Your mass in space | same as on earth |
| to convert grams into kg | move decimal 3 to the left |
| heavier objects have ___ friction | more |
| smoother surfaces have ___ friction | less |
| force that acts in the direction opposite of the movement | friction |
