Match the following vocabulary words with their definitions: question 1 options: rate of change in velocity, which is the change in velocity divided by the change in time the rate at which an object changes position when traveling in a certain direction force of attraction between all masses in the universe an object´s resistance to a change in motion force of resistance acting between objects in contact and tending to dampen their motion the rate at which an object changes position 1. acceleration 2. speed 3. friction 4. gravity 5. inertia 6. velocity save

Correct matching:

1 acceleration --> rate of change in velocity, which is the change in velocity divided by the change in time

2. speed --> the rate at which an object changes position when traveling in a certain direction

4. gravity --> force of attraction between all masses in the universe

5. Inertia --> an object´s resistance to a change in motion

3. friction --> force of resistance acting between objects in contact and tending to dampen their motion

6. velocity --> the rate at which an object changes position

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
