Science Chapter 1
sec. 1-3 notes
Question | Answer |
---|---|
Motion | When the distance between one object and another changes. |
Reference Point | |
When is an object moving? | When it's distance from a reference point is changing. |
International System of Units | System of measuring that all scientists use. (SI) |
How do you find speed? | Distance -------- Time |
Velocity | Speed in a given direction. (When you know the speed and direction of an object you know the velocity.) |
Constant speed | When an objects speed stays the same. |
How do you find distance? | Distance X Time |
When you want to find out the distance will travel in a certain amount of time and you know it's speed what is the formula? | Distance X Time |
Acceleration | Final velocity - Initial velocity --------------------------------- Time |
FACTS- Acceleration in everyday terms is the process of speeding up | FACTS- increasing speed, decreasing speed, or change in direction are all ways an object can accelerate |
