Hh
| Front | True or false: Changes in velocity occur when force vectors equal zero. |
| Back | False, if net force is zero there is no acceleration and without acceleration velocity does not change. |
| Front | Vector Quantity Example:Suppose you are walking at 5 mph west on a train that is going 30 mph east. What is your resultant velocity? |
| Back | 25 mph (just subtract) |
| Front | What is the difference between velocity and speed? |
| Back | -Velocity is the displacement divided by the time and there is always a vector direction associated with velocity.-Speed is the distance traveled in defined amount of time. Speed does not incorporate a vector direction. |
