The direction from the starting point and the length of a straight line from the starting point to the ending point.
What is displacement?
A description of both speed and direction of motion.
What is velocity?
This is speed with direction.
What is velocity?
The equation needed to find velocity.
What is v=d/t?
The length of the path between two points.
What is distance?
The ration of the distance an object moves to the amount of time the object moves.
What is speed?
What type of acceleration is a merry-go-round spinning around or a carousel and example of
What is change in direction?
The rate at which velocity is changing at a given instant.
What is instantaneous acceleration?
The change in acceleration if there is no change in velocity.
What is zero?
If a car travels 3 meters North, 2 meters West, 3 meters South, and 2 meters East, this is the DISTANCE traveled
What is 10 meters?
A car speeding up or slowing down is an example of what type of acceleration?
What is change in speed?
A ball dropping is an example of this.
What is free fall?
Movement in relation to a frame pf reference.
What is relative motion?
If a car travels 3 meters North, 2 meters West, 3 meters South, and 2 meters East, this is the DISPLACEMENT

A rollercoaster is an example of what kind of acceleration?
What is change in both speed and direction
This is what would happen to a cars total distance in two hours if its speed is doubled.
What is double the distance?
The total distance traveled, divided by the total time it takes.
What is average speed?
If a car travels 2 meters West, then 3 meters East, then 2 meters West, this is the DISPLACEMENT
What is 1 meter West?
If a river is moving at 4 m/s East, and a boat is traveling on the river at 3 m/s North, this is the velocity of the boat as seen from the shore. (Pythagorean Theorem)
What is 5 m/s NE?
An example of acceleration without change in speed.
What is moving in a circle at a constant speed?
The way in which displacement vectors going in the same direction are combined.
What is vector addition?
