|
what is motion? |
Motion is the speed of an object. |
|
|
What is speed and how do you calculate it? |
Speed is how fast an object is going/moving. To calculate speed, you do "distance/time"
|
|
|
What is acceleration? How do you calculate it? |
Acceleration is when an object is changing direction, increasing speed and decreasing speed. |
|
|
How can you identify if an object is in motion? |
If the object is moving. |
|
|
Speed and direction are two characteristics that make up _________________. |
Acceleration |
|
|
How can you identify if an object is accelerating or decelerating? |
If the object is changing direction, increasing or decreasing speed. |
|
|
A stationary object used to measure motion is known as a ___________. |
Reference Point |
|
|
What is average speed? How do you calculate it? |
Average Speed is different speed throughout the whole trip. You calculate it by doing "Total Distance/Total Time". |
|
|
When speed is mapped out on a graph, what do the following lines represent? A Horizontal Line- A very Steep Line- A slightly curved Line- |
*Horizontal Line- moving slow *A very steep Line- moving fast *A slightly curved Line- doesn't have a constant speed |
|
|
What is the difference between "Constant Speed and Average Speed"? |
*Constant Speed- same speed throughout the whole trip *Average Speed- different speed throughout whole trip |
|
|
Changing direction means an object is __________. |
Accelerating |
|
|
Are the planets accelerating in outer space? Explain. |
Yes, they are accelerating. Their constantly changing direction. |
