Forces Test Review
| Question | Answer |
|---|---|
| If given speed and mass OR time and force, what should you do first? | find the acceleration |
| use this to solve problems involving forces at right angles | SOH COW TOA |
| the unit for mass | kilogram |
| unit for weight | Newton |
| stays the same no "matter" where you go in the universe | mass |
| changes based on the amount of gravity present | weight |
| force exerted by a surface onto an object at a 90° angle | normal |
| in this state, the net force is zero whether you are moving or stationary | equilibrium |
| Only these can go on a free body diagram | forces |
| mass and acceleration are related this way | inversely |
| net force and acceleration are related this way | directly |
| the net force always points in the same direction as this | acceleration |
| action reaction pairs of force are equal in ___ and opposite in direction | magnitude |
| moving objects continue to move with the same speed in the same direction due to their | inertia |
| True or False: inertia depends on speed and location | false |
| True or False: inertia depends on mass | true |
| Is a force required to maintain constant motion? | No |
| Is a force required to accelerate? | yes |
