Motion
This is the change in position of object over time
What is displacement?
Velocity includes both speed and this
What is direction?
Acceleration is the change in this over time
What is Velocity?
The total length of the path an object travels is called
What is distance?
If a car travels km in 2 hours, this is its average velocity
What is 30 km/h
This kind of acceleration occurs when an object slows down
What is negative acceleration (or deceleration)?
This is the difference between speed and velocity
What is direction?
The velocity of an object changes if either of these two things change
What are speed and direction?
The area under a velocity-time graph represents this
What is displacement?
This type of graph shows how the position of an object changes over time and can be used to determine speed
What is a position-time graph?
This term describes a number that is not changing
What is a constant?
This device in a car measures acceleration
What is an accelerometer?
What is the main reference point we use to describe motion
What is Earth?
When velocity changes direction but keeps the same speed, this still happens to the object
What is acceleration?
An object moving in a circle at constant speed is still accelerating because of this type of acceleration
What is centripetal Acceleration?
