PHYSICS UNIT 2

6. is the rate at which the velocity is changing
7. constrains the object to motion in a straight path
8. tells you the total length an object covered while it was moving.
11. is the shortest distance from the initial to the final position (displacement)
12. When the speed of an object remains the same
13. how fast an object is moving
14. how fast and in what direction it moves
15. tells you how far away the object’s ending position was from where it started.

1. Putting pressure to slow an object down, an example could be the brakes of a car
2. longer length of time can be divided into a number of shorter periods of time, all of the same length
3. phenomenon in which an object changes its position
4. The speed at any instant speedometer gives readings of instantaneous speed in both mph and kmph
5. both constant speed and constant direction.
9. the total distance covered divided by the time.
10. are physical quantities that are unaffected by changes to a vector space basis (distance)
