Slow down.
300
The momentum of an object is the ______ of its mass and velocity.
What is product?
300

400
If a cat travels 3 meters North, 2 meters West, 3 meters South, and 2 meters East, what is the DISPLACEMENT
What is 0 meters
400
If a river is moving at 5 m/s to the East, and a boat is traveling at 3 m/s AGAINST the current to the West, this is the velocity as seen from the shore.
What is 2 m/s East or downstream?
400
A roller coaster is moving from path A to path B around a curve, but travels at the same speed the entire time. Is the roller coaster accelerating and how do you know?
Yes it is changing direction.
400
Speed is the rate of change of position as acceleration is the rate of change of ______.
What is velocity?
400
Draw a distance-time graph showing a runner speeding up, stopping for a few seconds, then speeding up again slower than before.
Steep slope, horizontal slope, less steep slope.
500
If a different dog travels 2 meters West, then 3 meters North, this is the DISPLACEMENT
What is 3.6 meters NW?
500
Velocity includes both speed and direction. Because of this, velocity is known as a ________.
What is vector?
500
What is the acceleration if a car starts at 15 m/s and slows to a stop in 3 seconds in the forward direction?
What is -5 m/s^2 forward?
500
Acceleration towards the _____ of a curved or circular path is called centripetal acceleration.
What is center?
500
Draw a velocity-time graph showing a runner speeding up, staying at a constant speed, then running slower than before.
Starting at zero, the line increases, then stays horizontal at that speed, then the line decreases to a slower velocity.
